What's wrong with this picture?
 
|
| |
Below is a copy of reference implementation from "Improved min/max" proposal for upcoming C++0x standard library ([link] JTC1/SC22/WG21/docs/papers/200 7/n2199.html).

Formal proposal: forward declaration of enumerations
|
| |
HI Everybody, after some positive feedback on the subject, I have prepared a formal proposal to add the possibility to forward declare (aka declare but not define) an enumeration when the underlying type is specified.
