My primary concern as a Boost.Test developer who want to employ FOREACH is 
portability. And simpler/less depencencies the code is/has the easier to 
achive a portability I need. And a secondary point is that IMO 95 % of users 
will only need this basic support. So why should they pay for something that 
only 5 percent of users need.

I do not think that's true. Essentially you only need an alternative 
implementation for begin and end.

It's would be just another level of compatibility: stl compatible containers 
only.
