Although this is platform-dependent, it's not really just one programmer's
opinion. For example, Bjarne mentions this in section 18.4 of The C++
Programming Language. To quote him (page 515 of the Special Edition): "For
example, it is easier to inline the application operator of a class than to
inline a function passed as a pointer to a function. Consequently, function
objects often execute faster than do ordinary functions."
