Let's compare these two equivalent code snippets:
C++:
auto start = std::chrono::high_resolution_clock::now();
doStuff();
auto stop = std::chrono::high_resolution_clock::now();
auto diff = stop - start;
auto ms = std::chrono::duration_cast<std::chrono::milliseconds>(diff);
std::cout << "Elapsed ms: " << ms.count() << " ms\n";
Python:
start = time.perf_counter()
do_stuff()
stop = time.perf_counter()
ms = (stop - start) * 1000.0
print('Elapsed ms: ', ms, ' ms')
In this case, the equivalent code is pretty similar, but modern C++ is generally more verbose out of the box.

And, to be fair, you only got it that small by giving up compile time safety though use of auto, which is one of the reasons you'd use C++ to begin with.

Auto deduces the type at compile time, so it's safe unless you intend the variable to be a base class of whatever the initializer returns.
|
|
|
|
|
But that's the problem, you didn't say explicitly what it should be. If the right side gets accidentally changed, nothing is going to complain if what it got changed to supports the same interface (not terribly uncommon in the modern world if lots and lots of operator driven stuff.)
If you explicitly say what it's supposed to be, then two things have to get simultaneous broken in the same way. If you don't, then only one has to get broken for potential silent errors.

If that was the case I wouldn't use auto . The situation you described is actually a feature of the auto keyword. It's pretty useful to only change the initializer without have to change the type declaration during refactoring.

I don't think the point of a language should to make it easy to refactor without having to really think about what you are doing and the potential silent errors it could introduce. Significant refactoring isn't common and it should be approached very carefully. Being explicit it always safer.

If you are regularly doing large refactorings, then something is already badly wrong and you have bigger fish to fry, IMO. Maybe better safe than agile?

Removing old versions of the .NET Core SDKs. Well over a dozen different versions, including previews for 1.0, 1.1, 2.0, 2.1, 2.2, and 3.0 preview.
There is a list of the current SDK versions at Download .NET Core (Linux, macOS, and Windows).
A painful process as you need to uninstall each one individually.

I remember trying to install Mathematica, which uses some library that is distributed with VC++, and there had been so many installs over the years that it just wouldn't work. I had to do a whole OS system wipe to get it to work.

I think they just hop to it, buck up and get the job done.

That reminds of one of the funniest comics I have ever seen. I think I scanned it once. I will have to do some searching and find it.
Anyway, it showed the easter bunny sh*tting out eggs, with several behind him. The earlier ones hatch and a little Jesus pops up and runs off. It still makes me laugh to think about it.
