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?

  1. For each is not standard C or C++ syntax. If you want to be able to compile this code in gcc or g++, you will need to create an iterator and use a standard for loop.
