Isn't it possible that the value space of, say,  a prime number type would
be narrower than an interpretation of it's lexical space would lead you to
believe? You're sure to have addressed this concern before, but I missed it.

Anyway, I hear what you're saying and don't disagree with the  "treat X as
of type Y for  this operation" paradigm.  But then you're still left with
the case where a lexically value representation does not sit well with the
primitive type I want (or was told) to use. Then I don't know if I made a
wrong assumption or you misrepresented to me the type that the lexical
definition was suppose to represent.  Or, it could be that there's a data
error.

I may have to take Tim's advice, and swear off  T-words.  Just leads to
lengthy threads.
