Looks interesting , one question:

Does the loading for the parsed/node tree generated dump avoid
evaluation? I mean, there is no need to reparse it, right? If so, then
you have a speed boost when loading pre-compiled ruby scripts and
sounds good.

How it handles reload of files (using load 'foo.rb' compares the mtime
of the pre-compiled file with the source file?)
