I've discussed with Clément doing something like cloning the Opal compiler,
or the Squeak compiler, so that it uses a fixed set of classes that won't
change over time, excepting the collections, and using as a benchmark this
compiler recompiling all its own methods.  This is a nice mix of string
processing (in the tokenizer) and symbolic processing (in the building and
optimizing of the parse tree).

Again, extracting a compiler from its host system would make it possible to
maintain a cross-platform version.  It could be left as an exercise to the
reader to port it to one's favorite non-Smalltalk dynamic language.
