I have Curried a function application by passing the partial tree to
dependent rules. (Note: I strongly suspect that my solution is really
way more complicated than it needs to be, sorry about that...).
Something like:
functioncall
: ( varOrExp nameAndArgs -> ^(FUNCALL varOrExp nameAndArgs) )
( curried_call[$functioncall.tree] -> curried_call )?
;
curried_call [ CommonTree t ] :
(apply[t] -> apply) ( curried_call[$apply.tree] -> curried_call )?
;
apply [ CommonTree t ] : nameAndArgs -> ^(FUNCALL {$t} nameAndArgs) ;
Hope this helps....
