Thanks Brandon!

I really like the addParam utility,

value val prompt = Question prompt (show val) (readCheck val)

addParam :: (Show a) => (funTy -> String -> qty) -> (a -> funTy) -> String -> (a
-> qty)
addParam qmakr fun string v = qmakr (fun v) (string++" "++show v)

prefix1 = addParam value
prefix2 = addParam prefix1
prefix3 = addParam prefix2

but my crusty and sleep-deprived brain is not really grokking the internal plumbing.

So I'm trying to get to grips with a simpler variation on the same theme, and I'm still failing. I'm trying to write something along the lines of

addArg :: nArgFn -> a -> nPlus1ArgFn
addArg fn a = (a+) <---- fn where
<---- = something which applies its right parameter to however many arguments it needs and feeds the result to the left parameter

in order to allow me to say

sum2 = (+)
sum3 = addArg sum2
sum4 = addArg sum3

etc.
