Did Haskell get significant whitespace from Python - doubtful as Python possibly wasn't visible enough at the time, but you never know.
Whitespace is significant in almost every language: foo bar /= foobar. Using indentation for program structuring was introduced by Peter Landin in his ISWIM language (1966), which is where Haskell picked it up from (via Miranda). See http://en.wikipedia.org/wiki/Off-side_rule Regards, Malcolm
