I concur that the use clause is under-used and over-maligned.

I do find it useful sometimes to be able to "with" a package without
"using" it, to control namespaces and prevent annoying collisions.

Overall, I'd just prefer that a "use" statement in a context clause
implied the corresponding "with" statement.
