Looks like not actually a phobos issue, but dmd/__parameters one:

http://dpaste.1azy.net/a09afb96
---
interface Test
{
    @property void setter(int x);
}

alias Type = typeof(&(Test.setter));
pragma(msg, Type);

static if (is(Type PT == __parameters))
{
    pragma(msg, PT);
}
else
    pragma(msg, "Error!");

void main() {}
---
Compilation output:
void function(int x) @property
Error!
---

__parameters seems to only with for actual function types and not for function pointers. Replacing "alias Type = typeof(&Test.setter);" with "alias Type = FunctionTypeOf!(Test.setter);" makes the bug example work. Similarly, replacing the first static-if in ParameterIdentifierTuple makes it work, but I'm unsure if this could break anything else:

line 832 traits.d:
--- static if (is(typeof!(func[0]) PT == __parameters))
+++ static if (is(FunctionTypeOf!(func[0]) PT == __parameters))

Oh, neat, I have thought & and FunctionTypeOf are quite equivalent. It can be categorized as Phobos/ParameterIdentifierTuple issue then.
