Perhaps.  I still have the feeling that sharing the same name is risking
confusion.  In particular, the fact that how 'process' should be used
depends on an import could make it harder for (1) those trying to learn
the workflow language by looking at and comparing Scheme examples from
various sources and (2) those trying to understand how Wisp maps to

Yes, sounds like a good idea to me too.
