That's another thing that AppleScript does (or did; I'm not sure if it's
still supported) -- Dialects. I could write a program using the English
Dialect, then change to the Japanese Dialect and all the keywords and syntax
structure would be magically translated (in 2-byte SJIS, of course; not a
big leap to Unicode). Very cool.

Do I detect a trend here? I can just see it now, "Apple Py"! Or perhaps the
biblical serpent on the tree of knowledge would be more appropriate...
