           Summary: is(T == function) does not recognize function pointers
           Product: D
           Version: 2.019
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: wrong-code
          Severity: normal
          Priority: P2

Consider the example:

template IsFun(T) {
  static if (is(T == function)) {
    enum IsFun = T.stringof ~ ": fun";
  } else {
    enum IsFun = T.stringof ~ ": not fun";
  }
}
void foo() {}
pragma(msg, IsFun!(typeof(foo)));  // (void())(): fun
pragma(msg, IsFun!(typeof(&foo))); // void function(): not fun

I expect both forms to be detected as functions.
