I've got an idea for a hack^H^H^H^H enhancement to the interpreter that I'd
like to try out. If it works, I was thinking of distributing it as a patch.
If somebody wanted to use it, they'd have to d/l the Ruby tarball, apply
the patch, build, and install.

Does this sound like a reasonable approach? Any catches I'm overlooking? Of
course the license would be the same as Ruby's.

What version of Ruby should I use? I suppose the stable 1.8.1, unless of
course 1.8.2 becomes production before I'm done, which is possible.

My plan is to simply check out the v1_8_1 sources from CVS, make the
changes, and make a patch with cvs diff. Is this the right approach?
