This is by design. The issue is to avoid double-translation, e.g.
when some component creates a Lisp file from some other source, that
is then compiled.
You want to be able to use compile-op and load-op, except that
the source-file will be the output of whichever create-lisp-op you're using,
and therefore already translated. In general, being able
to compose or not compose operations suggests that you shouldn't
double-translate.

I think you should correct test-grid-agent.
