But you need that special APL keyboard with the greek letters...

And if you think the classic IBM implementation on the "first PC" (the
5100) was funky, you should see Iverson's book
That said, I spent an entire summer of my youth doing all sorts of
interesting things in APL.
Like any arcane and esoteric knowledge, if you use it regularly, it's
second nature. If you only use it occasionally, it's hard to do stuff.

Come now.. think: a hybrid of APL and Matlab?
And doesn't APL elegantly represent inherently parallel constructs. It
might be the most appropriate language for parallel computing (at least
Iverson might think this).
