import std.traits : ParameterTypeTuple;

void foo()() {}

void main() {
    assert(!__traits(compiles, {struct A{ParameterTypeTuple!foo tmp;}}));
}

The above program fails to compile with this message:
bug.d(6): Error: template instance ParameterTypeTuple!(foo) does not match
template declaration ParameterTypeTuple(func...) if (func.length == 1 &&
isCallable!func)

Replace ParameterTypeTuple!foo with a simple type, and things work wonderfully.
