i wish the GCC guys would all read that. ;) i will swear on my life i've 
seen type_info::name() returns two different strings for the same type, 
depending on their creation scope. That was way back in 3.0/3.1, too, 
so maybe it doesn't happen anymore.

In any case that page only applies to gcc. According to C++, what name() 
returns is UNDEFINED. Scott Meyers covers this in detail in one of his 
books. The way he puts it, even an implementation in which name() 
returns an empty string for every class is fully compliant with the 
standard. Not useful, but compliant.

That still requires instantiating it, a limitation i haven't ever needed 
in a factory implementation.
