That's interesting how C# treats classes and structs differently.
As far as implicit type conversion in C++ goes, a constructor that takes a single argument can be tagged explicit to the avoid unintended creation of an object. I've rarely used implicit construction because it can make the code opaque.

At the end of the day, it's still sacrificing ease of maintenance for better CPU performance.
No matter how you slice it, that's not a trade-off I'm comfortable with, given the average amount of defects per KLoC in C++ code.
Then again, I avoid writing C++ for specifically that reason.
(that and my hate for having to maintain and patch a couple of C++ projects that have long been abandoned by their creators)

We use var all the time at our shop, where applicable.

Var should be used whenever the type is obvious from the RHS. Most of the time, nobody cares about the specific type of a variable, yet explicitly declaring the type forces maintainers to read it 100% of the time. It's also less DRY: it would be silly to say, "Today I washed my car today".
The counterpart is a newer feature that lets us instantiate without the explicit type, which arguably should only be used when the type is obvious:
private Dictionary<string, ienumerable<int="">> _lookupTable = new();

I used to explicitly type all my variables until recently when it seems to have become fashionable in my department to use var. I don't normally follow coding fashions unless they make sense, and this sure makes the code look cleaner. And as long as IntelliSense knows what type it is and shows me the correct properties and methods, I'm happy.
If you think 'goto' is evil, try writing an Assembly program without JMP.

In what way would the underlying type change? I believe that it is a change solely to the warnings/errors produced by the compiler. Although I guess some code copied from Stack Overflow may break 
I've wanted this since C# 1.0. Any run-time error you can prevent at compile time is something that I'm for, although with all the semantic sugar they're adding, I'm worried about diabetes.
I agree it's best for greenfield, I'll bet most older projects aren't updated.
I wish they had made it optional by a postfix ! instead the way they did way back when with a preprocessor, but I see that acting a lot like the const poisoning that happens with C++ when you make something const so I understand why they just yanked off the band-aid.

It has come to my attention that you did not read the memo.
I do not know what to tell you. We all did a zoom call and agreed on this months ago.

Did I ever mention why I hated MSFT? and most of their products?
THIS. Exactly This!
The last straw was when they stopped adding changes to the 16 Bit C/C++ compiler that they were putting into the 32 bit version. Our lead dev made a 32 bit library that we were forced to write a Thunking layer to use. He used almost every new feature he could. In the end, I forcibly recompiled the code using a Borland 16 bit compiler.
The ONE thing I LIKED about Oracle was that for DECADES we would simply DUMP our DB and Code.
Import it into a newer version, and it worked. Hundreds of upgrades, and we barely ever ran into something that no longer compiled.
Something I can honestly say NEVER happened with MSFT stuff. From VB breaking every version, to the above, to MSSQL T-SQL changes. (Heck, SqlCmd has a :Connect command. Try to use it in Azure hosting! Because it does NOT support choosing the Database. So it fails. It's as if ONE HAND has no idea what the other is doing).
Good ideas are great... But going in to make a small change to a system, and finding out you cannot even begin to recompile it because of the new compiler. Imagine if Linux was built on those precepts!
I feel your pain!

I used to criticize MSFT. Then I built a few projects with NPM libraries and felt the true pain of uncoordinated independently maintained software tools and libraries from everyone wanting to contribute a weekend project and then move on. Suddenly MSFT seemed like the best thing every. One company to address security and ensure all of your dependencies are upgraded at the same time and work together is heaven compared to the past several years of "free" libraries.
Who am I kidding, I still criticize MSFT. But a lot less now.

Had heard an anecdote related to the famous lexicographer Samuel Johnson. Once he met a novelist and said that all the words in that novel are taken from his book, because Johnson had indeed compiled a dictionary, a lexicon.
Now all the words in the word list of NYT will indeed be taken from Samuel Johnson's lexicon, compiled more than 200 years ago. Except for those words introduced into English since then. How can NYT stake claims for the word list?
