Assigning this to myself. There's a whole host of traits that will be coming.

Would it be possible to get the parameter types of a lambda which has some parameter types specified and some not? In that case I would expect "void" to be returned for those parameters that don't have a specified type.

(int a, b) => a + b

This probably expands to:

void func(T)(int a, T b);

Therefore it has 1 template parameter. If you use __traits(getTemplateParamCount, lambda) it will return 1.

I'm interested to know if std.traits.ParameterTypeTuple (or similar) would work with lambdas with both regular types and templated types.

Well I'd imagine changing what ParameterTypeTuple does right now would probably break a lot of code. So it's probably best to write a new set of library wrappers for the new traits. It's not very easy to combine all of these different types nto a single template.

It seems https://github.com/D-Programming-Language/phobos/pull/3394 takes care of this all.

Recapping from the PR just closed (temporarily):

-----
Ok, I'll start a discussion in the forums soon with a proposal of a (sub)set of the new traits and see which ones we really need, and whether we could implement as many of these in the library instead of adding additional compiler code. Closing for now. :)

I'll bring this up in the forums soon.
