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.
