It seems inside the template constraints functions must be called with a
trailing (), unlike from other functions:


bool foo() {
    return true;
}
void bar1(T)(T) if (foo()) {} // OK
void bar2(T)(T) if (foo)   {} // error
void main() {
    foo;                      // OK
    bar1(0);
    bar2(0);
}



dmd 2.063alpha gives:

temp.d(5): Error: constraint foo is not constant or does not evaluate to a bool
