I can't say if C++ standard requires
const_T1_reference
extract_key_imp(const_pair_reference r_val)
{ return r_val.first; }
creates a temporary and returns a reference to it. On the other
hand, I can't tell returning a reference to r_val.first directly will
cause any harm.
FWIW, icc 10.0 also creates a temporary and returns a reference to it.
