LiveAST merely takes a static Ruby parser and electrifies it with the
Ruby runtime. The weirdness you observe is the lack of a full-featured
cross-implementation parser for Ruby 1.9. This project is only a
messenger for that weirdness :)

Ruby needs a parser:

(The current implementation of LiveAST is different from the hacky
prototype mentioned in that thread, though it is still small.)
