Hello all

Anyone got an opinion on this.

I looked in boost, and there doesn't seem to be forwards for this.

Suppose I am writing my .h file, instead of including shared_ptr.hpp i
could just forward it using the following:

namespace boost {
template <class T> class smart_ptr<T>;
}

My concern is compilation time, as im going to do this in 1000+ .h files.

If, in the user code, the function returning smart_ptr is not used, this
could save some compilation time, but then again is that enough to justify
a forward ?

Regards

Rune
