Hello,
I would like to improve usage of boost::any with text (char*) constants. This would be the goal:
boost::any foo("foo");
This is not a char*. There is no problem putting a char* in a boost::any. It's a const char[N]. An array. To insert an object into a boost::any, the object needs to be copyable. Arrays aren't. The end.
Arrays are badly-copyable because the C++ committee has never fixed them from their half-done status (unlike struct). Maybe we should take the lead and make a special case for allowing array objects in an boost::any. (Note for the string case, we have to include the terminating NUL, so the rules won't be irregular with non-character types, and for non-string arrays that just happen to have a character type for elements [i.e. due to template code].) -- Daryle Walker Mac, Internet, and Video Game Junkie darylew AT hotmail DOT com
