I don't think that's really necessary.

My plan for reverse-currying was to simply use another tag, e.g. `rcurry',
and that solution serves for other extensions too.

Unless someone has a pretty good idea of _what_ such an extra field would be
used for, it seems like just wasted space to add it now.  If in the future
it's discovered that we really do want a new enhanced curry function, we
could add it using a `super-curry' tag or something [and even then, existing
applications that don't need that (hypothetical) functionality might want to
keep using the plain `curry' tag just to save space].

Yeah.
