So... language/compiler example?

I am going to keep poking until something is decided for note.  ;-)

What about using SQLite to store the intermediate representations?  It
has a number of benefits such as quick searching anywhere in the
hierarchy tree, keeping the intermediate representation (possibly very
large) on disk instead of in memory, etc... and so forth.  Could
abstract it out to handle normal in-memory representations too for
systems that cannot or prefer not to link in SQLite.  I had actually
starting doing this same thing recently for my play-language and it is
showing to be a surprisingly large boon.
