'Point free' is standard mathematical terminology for nothing more
than the style of defining functions without making direct reference
to the elements the functions act on.
This style is exemplified by category theory and the reason it's
called 'point free' rather than 'element free' is that

Here, I think an examples worth a thousand poierr, words. This one
comes from YAHT. Consider the two implementations of the following
function:
lcaseLetters :: String - String
lcaseLetters s = map toLower (filter isAlpha s)
lcaseLetters :: Strint - String
lcaseLetters = map toLower . filter
