I wrote the following program a while ago :-

This compiles. When I run it however, it exits with the stack exceeded message.

Why? Are the function composition operators more than syntactic sugar for the brackets?

Your problem is probably in this expression:

sumFacDigits n `div` 10

Becuase function application binds tightest, this is the same as:

div (sumFacDigitss n) 10

whereas your original was:

sumFacDigits (div n 10)

So your transformed program is not the same as your original. I hope that helps. -Antoine
