The grammar *could* have a bearing on what proto operators are 
considered, so long as you specified the grammar as the second parameter 
to proto::domain<>. If your grammar doesn't allow comma, then proto's 
comma operator is ignored, leaving only C++'s build-in comma.

If that's not the problem, you'll have to post a self-contained repro of 
the problem so we can track it down.
