It's also worth noting that (ostensibly) the first complete
microcomputer system (keyboard, printer, storage) was the MCM/70, using
an 8008 implementing APL (not BASIC!).
I'll say it again--a programmer who thinks in APL is very different from
one who thinks in BASIC, Fortran, C, Pascal, etc.
So of course, an APL program would look unintelligible to a non-APL
