Boost :

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


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
