That too is my take on C++. I have done several projects in C with compilers of various capabilities, even going so far as to finish a re- write of the os9 c.prep 20 years back, and which lasted until someone else found a missing piece about 3 years ago & added it to my src's. But for ultimate speed, assembly to native code cannot be matched. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
