This will be a nightmare for code maintenance. It's hard enough keeping code sensible so that any dev can step in and understand and safely maintain it, what with all the syntactic sugar being added. Allowing this to be non-standard and ad-hoc will just massively increase the surface area of confusion.

In C# and C++ an "in" and "!in" operators. For example, if we have"
if(var1 == param1 || var1 == param2 || !(var1 == param3))
{
}
to be able to translate to:
if(var1 in (param1, param2, !param3))
{
}

And an isnt operator, to avoid !( x is y ) ?

Can we also have the redneck version called aint?

How about the "aint not" operator?

Well, let's not, else we may wind up with multiple inheritance problems.

YES !!!!
and as in :
if (ch in [A..Z,0..9])
as it is in Pascal.

I make a static Hashset for that (C#).

That's cool. The build-in contains/subset functions are native and fast.

Well, yes, but ... In all the Pascals I have been in touch with, it is implemented as a bit map. A few orders of magnitude lighter, I guess.
There are several other Pascal features I certainly would welcome in C#. Such as decent enumerations, as a first class data type - not just symbolic names for integers, that cannot even be used as integers! In particular: The enum we are offered cannot even be used as an array index type.
Closely related: I would welcome Pascal style subrange types. Define a type Year = 1900..2050, and assigning a value outside this range to a variable of type Year is caught by the runtime system (or the compiler, if it can be determined statically).
Related to this: An array with index type Year, so valid index values run from 1900 to 2050.
To go a little beyond Pascal: I wish we had a mechanism for defining incompatible types: If I could define 'new type Speed = float;' and 'new type Volume = float;', variables of type Speed and Volume would be incompatible, and the compiler would give an error if you try to add them (without a proper operator definition for the two types, or an explicit cast).

Oh, well, yeah, for individual (ASCII) characters a bitmap or similar may be best. I was thinking of a more general technique.
Edit: As in making a Hashset and putting various (UNICODE) quote characters or whitespace characters in it to test against.
Yes, there are many things Pascal does which are handy. But I haven't used Pascal in decades, not since learning C.

Pascal had bitmaps as a first class type ('SET OF'), with operations for inserting and removing elements, intersection / union / difference operators and membership tests. I guess that the C code I have written for doing the same things were at least as efficient as the Pascal compiler could have done it (it probably would have added a lot of range tests), but I certainly have often missed the syntactic simplicity of Pascal for such operations!

I am rusty in C/C++, but thought typedef would do that for you in C and C++.
Need a cast to assign between the typedefs even if they are both native float.

Convert it to a function
In(var1, param1,…)
Or throw some functor at it like
In(var1)(param1,… )
Is(var1).in(param1…)
Could be a lot slower, though.

My daily drivers are TypeScript/ECMAScript (JavaScript). Since JS is now governed by ECMA, having a committee behind it is a great thing for helping the language to continue to mature in a reasonable way. So, my wish has been answered.
But, if I had to pick a wish-list for this ecosystem, it's less to do with the language and more to do with the developers. Despite this ecosystem finally starting to grow up, there are 10,000 packages to clip your toenails, for instance, and 99% of them aren't worth much. And despite the efforts of the language itself growing, due to the enormous popularity of JavaScript, there are still a ton of folks who pretend to know the language but are just script kiddies.
For those wondering why I didn't say something like TypeScript to WASM compilation.... there's already a project that does that with a subset of TS suitable for this.

C# -- Multiple inheritance.
And a C-Preprocessor which is more flexible, for use with things other than vanilla C.
I've wanted this since doing PRO*C back in the 90s.

If you want C++, you have it. There were good reasons for including multiple inheritance in C++ at the time, and equally good reasons why C# and Java did not include it.

Personally, I consider the C preprocessor in its current form to be poorly engineered. Because its definitions are global, the inclusion of a header file can totally change the semantics of a module. Yes, it has its uses, but on any large project it requires a lot of coordination to avoid definition clashes etc.
