Hi,

Hello.

Is the following program supposed to compile with the new MPL?

Probably not.

But, maybe I was mis-using equal_to ?

equal_to<...> no longer accepts bool_<...> or any expressions resulting in bool_<...> as a template argument, since bool_<...> does not contain a typedef named tag (for numeric_cast<...>). I don't have the MPL book, so I don't know the rationale behind it, but working around it should be as simple as an eval_if<...> statement.
