My current design for such a beast is based on the assumption that not
only you need a parser, but that the code of this parser is more easily
written in Ruby, more easily understandable in Ruby, and more easily
reusable in Ruby. From there, I envision two possible strategies of
implementation of the parser in that Java-based interpreter:

	A. Keep the "Ruby Parser in Ruby" as a reference implementation
	and translate manually into Java.

or

	B. Make the "Ruby Parser in Ruby" parse itself into the internal
	code-tree format used by the Java-based interpreter, and then make
	that code-tree part of the interpreter, such that on startup of
	the interpreter, the parser is pre-loaded.

Before that "Ruby Parser in Ruby" is written, I don't move by an inch.
Note that I don't know shit about parsers, so I leave this to someone
else.
