Do you think the library should be accepted as a Boost library?
Yes
Did you try to use the library? With what compiler? Did you have any problems?
icc 8.1 linux gcc 3.3 linux gcc 3.4 linux gcc 4.0 20050418 linux no problems
What is your evaluation of the documentation?
I agree that it shouldn't be named "foreach", although it is very much keyword-like, but I think a "#define foreach BOOST_FOREACH" in the documentation examples would encourage its use. I'd like to see a few notes about possible performance impact of BOOST_FOREACH because of confused optimizers etc. in the documentation. there's almost none but you have to find out yourself if it's not documented. (I did so with icc and gcc. innerloops looked the same or almost the same. gcc generates some overhead outside the loop: a non-inlined call to addressof and 12 bytes of additional reserved stack space, which can be problematic with deep recursion)
What is your evaluation of the potential usefulness of the library?
very convenient, will use it
Are you knowledgeable about the problem domain?
