The following program gives me

Is this because char etc can be converted to uint? Shouldn't the
template specification make this unambiguous?
import std.traits;
struct S {
this(uint i) {}
this(C)(C c) if(isSomeChar!C) {}
}
void main() {}
struct S {
this()(uint i) {}
this(C)(C c) if(isSomeChar!C) {}
}
should do it, though it (and workaround) looks like a bug to me.
With the empty templated this, I get other errors though:
"t.d(5): Error: constructor t.S.this conflicts with template
t.S.__ctor() at t.d(4)"
struct S {
this()(int a) {} // 4
this(int a, int b) {} // 5
}
Same logic here once you have template constructor, all others need to
be template, empty spec is a trick to get anything to be a template. And
in this example you really do not need empty spec () in 4.
