Just wanted to add to my prev posting.
I think cannot_visit should be available in apply_visitor as well.

apply_visitor< cannont_visit<type1>, cannont_visit<type2> >(v);

It'll give a finer visitation control at the
invocation time in addition to the declaration time.

Eric, any chance to get in v1.31?
