Nov 10, 2013 at 17:05 comment added Gill Bates Disagree - a fact that program is composed from 'pure' functions doesn't mean that it don't iteract with outside world, it's mean, that every function in a program for one set of arguments will always return same result, and this is (purity) a big deal, because, from practical view - such program will be less buggy, more 'testable', successful execution of functions could be proved mathematically.
