it's a "bug" in proto?

I think the problem is, that proto's operator enable/disable facilities only
"saw" the equal_to operator, but obviously no terminal type for it's right
and left hand side.
It looks to me as a bug in proto as well. because with my "fix" something
like this:
i == i + i
didn't work anymore.
So, it looks like proto's enable facilities do not look "deep enough" in the
grammar. that is, it somehow misses the template arguments to equal_to.
