That would have to be quite the subset. The Ruby parser alone is almost 12kLOC. I've implemented entire languages in 1/10th that.

mruby (http://mruby.org/, https://github.com/mruby/mruby) is the official attempt to do just that. Depending on what you count it's around 30-60kLOC. It has a standalone bytecode compiler, so the parser (which is "only" 6kLOC) doesn't have to be a part of the runtime.
