Does enum have any effect on functions?
Is this:
mixin (Constant!("ln2"));
package enum T ln2(T)(Context context) {
return log(T.TWO, context, false);
}
different from this:
mixin (Constant!("ln2"));
package /*enum*/ T ln2(T)(Context context) {
return log(T.TWO, context, false);
}
The spec says that enums are used to declare constants. I'm not
sure what it means for a function to be constant. My guess would
be that the value of the function is CTFE'd and that value is
stored as if it were a manifest constant, but that's not what
happens. The enum functions operate exactly like the non-enum
functions.
So either enum functions are different in some way or they're
not. If they are different that should be in the spec. If not,
enum before a function declaration should not be allowed.
