I brought up this issue a few weeks ago. I was thinking we should be able to write

rvalue(_1)

or maybe

cref(_1)

to pass rvalues.

The problem is that the BPL operator() looks like this: template<class A0> R operator()(A0& a0) AFAIK there's no way to insert a const there, other than providing the full 2^N overload set. -- Daniel Wallin
