08:38 <kuba> hi guys, i am trying to find the 'lexer' bit in the opal source code but so far without luck; where are the keywords defined?

10:57 <kuba> ok, so after a morning of digging - (for anyone interested) - I figured out that Opal is using Parser gem which has a Lexer defined in Ragel

10:59 <kuba> so if you want to tinker with keywords like I do, help yourself in https://github.com/whitequark/parser/blob/master/lib/parser/lexer.rl
