For reference, an obfuscated jar of the Kahlua runtime is currently at 24 KB.
Using Hashtable wasn't an option due to semantic reasons -
implementing next would get tricky. Instead a custom hashtable was
implemented, trying to mimic the standard lua implementation.

(As a note, I have written apps for J2ME that had to fit in 64 KB.
Those were painful times.)
