Re: Mission impossible
If it doesn't work, hack it:
struct S {
static void func(T)(uint a, T t) {
}
static void func1() {
}
alias func=func1;
}

I suppose __traits(getOverloads) doesn't work because of a bug ?
The template hides any other overloads that func() has:
IF it is defined before it. If it is defined after it, it does not (but
it is then possible that the non-template version hides the template one).
The problem is that S has two members called "func". One is a function,
and the other is a template. "getOverloads" is not built to distinguish
between the two.
I'm not sure if its a bug though
What else is it?

That'd be https://issues.dlang.org/show_bug.cgi?id=16206. Reorder
the two functions, and it works.

It looks like having the templated function makes it so that
__traits(getOverloads, ...) gives an empty AliasSeq. It's probably something
that got missed when it was made possible to overload templated functions
with non-templated functions.
