Bug 2407 – function pointer as an enum's base type doesn't work

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.
