Word description Partially applies p, q and r to x.
Notes The following two lines are equivalent:
[ p ] [ q ] [ r ] tri-curry [ call ] tri@
[ p ] [ q ] [ r ] tri
Higher-arity variants of tri can be built from tri-curry:
[ p ] [ q ] [ r ] tri-curry tri == [ p ] [ q ] [ r ] 2tri
[ p ] [ q ] [ r ] tri-curry tri-curry bi == [ p ] [ q ] [ r ] 3tri
The combination tri-curry tri* cannot be expressed with the non-currying dataflow combinators alone; it handles the case where you have four values a b c d on the stack, and you wish to apply p to a d, q to b d and r to c d.
