With some background in assemble instructions and C programs, I can visualize how a compiled function would look like, but it\'s funny I have never so carefully thought abou
"Compiled classes" mean "compiled methods".
A method is an ordinary function with an extra parameter, usually put in a register (mostly %ecx I believe, this is at least true for most Windows compilers who have to produce COM objects using __thiscall convention).
So C++ classes are not terribly different from a bunch of ordinary functions, except for name mangling and some magic in constructors/destructors for setting up vtables.
