called_from 0.1.0

Extention Module 'called_from' provides called_from() global function which gets filename and line number of caller. In short: require 'called_from' filename, linenum, function = called_from(1) is equivarent to: caller(1)[0] =~ /:(d+)( in `(.*)')?/ filename, linenum, function = $`, $1, $2 But called_from() is much faster than caller()[0].
