I'm sure this has been asked before, but searching the archives I cannot find anything. Is there some tutorial material on result_of anywhere? The boost documentation simply points to n1454, which doesn't contain much in the way of examples, and the TR1 document (n1647) which has no examples at all.

Q: What do I write in the space marked ??? below:

template ??? apply( F f, A1 & a1, ..., An & an ) { return f( a1, ..., an ); }

A:

typename result_of::type.

Is there any way to handle implicit conversions?
