[boost] [utility] boost::reset

Hi,

I just wrote a small helper function to clear a container. Well, OK, we 
already have that, do we? For a container 'cont':

   cont.clear();

But this doesn't neccessarily free the memory allocated. The "usual" 
workaround is:

   Cont().swap( cont );

But Cont (the type of the container) is sometimes rather large and the 
code doesn't communicate well what I intended.

I thus wrote the following small helper:

   template< typename T > void reset( T& t )
   {
     T().swap( t );
   }

Would this make a good addition to boost.utility? Any comments welcome...

Regards, Daniel
