What is your language feature wish list?
-
What languages, wishlists do you have for your favorite programming languages? C and where applicable, C++: preprocessor definitions that are private to the actual (in this case header) file they are contained in. namespaces that are private to their header. and/or a standard way to separate the implementation of templates into a cpp file a way to predeclare templates (not template instantiations) such that you can access them before they are defined. C#: Mainly I want its code generation to have DSL (domain specific language) capabilities. This means you can create code generation facilities that introduce new keywords into the language, for doing things like AOP and cross-cutting functionality orthogonal to any specific class. The only problem with it is I think it would be overused.
To err is human. Fortune favors the monsters.

Some of your desiderata can already be approximated in C++, at least.

With the exception of conditional compilation, I have little use for the preprocessor in C++. Defining an anonymous namespace inside a named namespace will allow scoping of C++ (not preprocessor) definitions even in a header file.
honey the codewitch wrote:

You already have something close to this in C++ - define a namespace in the header with an anonymous internal namespace. Only functions declared in the (named) namespace may access the definitions in the anonymous namespace.
namespace foo
{
namespace
{
int bar();
}
// bar() accessible here
}
// bar() not accessible hereFreedom is the freedom to say that two plus two make four. If that is granted, all else follows. -- 6079 Smith W.

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.

How did I not know about that? Thanks!

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

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](https://www.assemblyscript.org/) that does that with a subset of TS suitable for this.

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

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.

I'd like to have a language/IDE that can sense my mind, interpret what I want to accomplish, and generate the code required to fulfill my wish. Is that really too much to ask, in this era of AI domination?
