So here's the way I'm reading this:
Original:
curry_call is the function body you're constructing, which is itself just a
one liner which calls the symbol FUN with the appropriate substitutions.
Yup. With a bit more infrastructure you could probably modify it so
that multiple curries collapsed into the equivalent single curry.
Yes I could see how one would do that - if the match.call detects a
Curry as the first function being called, we would short circuit the
usual evaluation into a different path which properly collapses all the
nesting.
It's interesting how R offers these facilities to override the usual
evaluation order, but if one does that too much it could easily become
confusing. I was looking at Rpipe the other day
(https://github.com/slycoder/Rpipe) and the way he implements it is by
defining his own Eval.
