Boost :

Just a note to say thanks for boost::function ;-)

Just completed some timings of the cost of a boost function call using a
boost::function<void (void)> and a raw function pointer versus inlining the
function's code directly into the source.

For my circumstances (your mileage may vary):
        Calling via raw function pointer = 314 microseconds +/- 1
        Calling via boost function variable = 328 microseconds +/- 1

Only 14 microseconds of difference. Nice work, I was expecting much more.
