I can reproduce the problem with gcc 3.3.3 (cygwin), but the problem
does not reproduce with Visual C++. I'm a bit at a loss here. There is
really no problem with BOOST_FOREACH or with its use of Boost.Range or
with Boost.MPL that I can see. It would seem to be a compiler problem. I
don't know why ADL is finding a class name, and I'm not sure what a
suitable work-around should be. I'll give it some thought.
Actually, I seem to recall reading about this problem (there might even
be a defect report already). If anybody can refresh my memory, I'd
appreciate it.
