I believe #test stems for unix command line, and thus appeals to that
flavor of developer. It is a much more concise notation the
File.exist? or File.__fill-in-the-blank__. And though I like it's
brevity it has two aweful shortcomings 1) it is rather archaic and
cryptic and 2) it's bound to get clobbered by test frameworks!
