Would it be possible/usefull/fast to implement expression overloading instead of operator overloading? What I call "expression overloading" is like: float add_mul_func(float a, float b, float c) written 'a * b + c' or 'c + a * b' { version d { return a * b + c; } version x86 { asm { FMULADD c,a,b ... } } } |

Not at the moment. Yes. Yes. But whether it's desirable depends on the effects it would have on the language. I suspect they would be quite significant, so don't expect to see it in 1.0. But having an interest in such things - see my article Fast String Concatenation in June's C/C++ Journal - I would be interested in seeing this issue explored at a later time. -- Matthew Wilson Author: "Imperfect C++", Addison-Wesley, 2004 (http://www.imperfectcplusplus.com) Contributing editor, C/C++ Users Journal (http://www.synesis.com.au/articles.html#columns) STLSoft moderator (http://www.stlsoft.org) "If I'm curt with you it's because time is a factor.
