I agree -- even those slightly interested should take a look -- the
downloads are relatively small: about 2.6MB for J (full evaluation
version with doc) and under 1MB for K (demo version with doc). I
especially like the way they define "nouns", "verbs", "adverbs", etc
which are used to form "sentences" (functions).
