           Summary: function pointer as an enum's base type doesn't work
           Product: D
           Version: 2.014
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: rejects-valid
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: marcin.wcislo@gmail.com


Take a look at this snippet:

1. void foo() {}
2. void bar() {}
3.
4. enum Enum : void function() {
5.     FOO = &foo,
6.     BAR = &bar
7. }
8.
9. int main() {return 0;}

error message:
enum.d(6): Error: Integer constant expression expected instead of (& bar) < (&
foo)
enum.d(6): Error: Integer constant expression expected instead of (& bar) > (&
foo)

However, this one works fine:

1. void foo() {}
2. void bar() {}
3.
4. enum Enum : void function() {
5.     FOO = &foo
6.     //BAR = &bar
7. }
8.
9. int main() {return 0;}

Docs say that 'Type' can be the base of enum, where 'Type's' definition is in "Declarations" of 2.0 and includes function pointer, so I guess the first case is the bug.
