"Impure" should be on parameters so you can do dataflow in the presence of FFI.

So you basically need better mechanisms.

But then you have to analyze the needs first (e.g. the desirable semantics that currently are avoided) All of then.

Adding one hack after the other is not the best approach.

Eventually the real solution is automatic inference, with the user using explicit attributes at the top-level where they are desired, and the compiler will take care of the rest.

Yes, but you need a model of the semantics you are looking for.

Agreed.  The time when you want to explicitly use these attributes is if you want to enforce @nogc, pure ...

As it turns out, it is a good idea to enforce these from the start, rather than after you've written your program.

At the same time as enum x(T) = 2; I think.

Nah, array type suffix goes before the template argument list.

Is this documented?

It is results!T[2], not results[2]!T.

It's really needed to keep C++-compatible as possible otherwise too few people are going to use it. If C++ wasn't C-compatible do you think it would be a successfully language it is today? I don't think so.

What is needed?

D is not c++-compatible anyway. and talking about compatibility: it's what made c++ such a monster. if someone wants c++ he knows where to download c++ compiler.

the last thing D should look at is c++.

D is ABI- and mangling-compatible with C++.

Well what can I say? I'm glad you're not making the decisions.
