> You can't use java's classes and perl's regexes and haskell's laziness. You have to pick the whole toolbox together, and take it as it is. Which is (i) a pity, and (ii), not entirely true.

Of the top of my head, I have 3 example of language implementation small enough to be customized, ported, or otherwise scavenged for ideas.
