Re: [boost] Improved boost::any

hello and good day,

Yes, this is actually not unlike the my own implementation of "any".  But  
rather than limit myself to objects that fit in sizeof(void *) bytes, I  
keep an aggregate member whose size is governed by a template parameter  
with a default value of sizeof(void *).  This way I can arbitrarily  
specify the mininum size at which objects are heap-allocated.  I think  
this is probably the way to go for discriminant unions..  the typelist  
solution is just to messy for my tastes, and boost::any is too  
consumptive.  Anyone interested?

sincerely,
Phillip
