I have had some experience with Qt's analogue of Variant - QVariant. 
Variant looks superior to QVariant in almost all respects. Where it is 
lacking is implicit conversions from static types:

void foo(Variant v);
foo(1);

Quite a nuisance if one wants to use Variant exclusively.

Another QVariant feature I would like to see in Variant is a constructor 
taking the type descriptor and a void pointer to the value. For example, 
it is needed for constructing Variants from variadic arguments.
