Another Currying Example in Marvin

currying

Please see my previous post before if you haven't done so.

I've quoted David Mertz's article Charming Python in my previous post. In that article, (besides other things) a Haskell function is curryied as:

computation a b c d = (a + b^2+ c^3 + d^4)

Then it is filled as follows:

fillOne   = computation 1
fillTwo   = fillOne 2
fillThree = fillTwo 3
answer    = fillThree 5

and the answer is 657. The same thing can be done in Marvin:

[ swap 2 ** + swap 3 ** + swap 4 ** + ] :computation
[ 1 \computation ] :fillOne
[ 2 \fillOne ] :fillTwo
[ 3 \fillTwo ] :fillThree
5 \fillThree
