not sure you would get 2 bytes on all platforms.  most are 4, and most would
be floating point.

basically, if your program is more than one line long, it isn't 'APL'.  :)

that's the point.  It is most useful for math stuff on arrays.  But you have
to learn a bunch of operators to become efficient...
