The "ruby" source?  parse.y is compilable unambiguous grammer
description. ;-)

Seriously, Ruby had been too "hot" to write human readable "clear
specification".  Recently Ruby (at least 1.7) grammer and behaviors
are becoming relatively stable, so that such attempt may be
reasonable.

I would welcome volunteers for such effort, as long as the process for
me to upgrade the spec. is provided.
