Hmmm ... that's certainly do-able, though I'm not sure how much it helps
the use-case you suggest.  The search path still has to be set at the
top of the module script, no?

However, I like an explicit option of this sort a lot better than the
automatic version Greg was suggesting ... I'm willing to do it if people
want it.

One problem is that we'd have to make CURRENT a reserved word to make it
work exactly like that.  Can anyone think of a variant syntax that
doesn't need a new reserved word?
