Visual c++ "for each" portability

Question

I only just recently discovered that Visual C++ 2008 (and perhaps earlier versions as well?) supports for each syntax on stl lists et al to facilitate iteration. For example:

list<Object> myList;  for each (Object o in myList) {   o.foo(); } 

I was very happy to discover it, but I'm concerned about portability for the dreaded day when someone decides I need to be able to compile my code in say, gcc or some other compiler. Is this syntax widely supported and can I use it without worrying about portability issues?

Answer 1

I wouldn't use that. While it's a tempting feature, the syntax is incompatible with the upcoming C++0x standard, which uses:

list<Object> myList;  for (Object o : myList) {    o.foo(); } 

to do the same thing.
