Hmm, yes, perhaps it should.  Although that does make things slightly less
convenient for the simpler case when you're not interested in the values
returned.

   [% CALL hash.delete('foo') %]  vs [% hash.delete('foo') %]

I wonder if it would be better to have a separate method, say remove(), which
returns the values, leaving delete() to simply delete them and throw the
results away.
