I learned it about 15 years ago (OpenAPL, running on a Solaris workstation with a modified Xterm that handled the APL characters).  Nice.  It made a handy tool for some cryptanalysis programs I needed to write.

I wonder if current APL implementations use the Unicode characters for APL, that would make things easy.

One of the strangest programming languages I've used is POP-2, which we used in an AI course (Expert Systems) at the University of Illinois, in 1976.  Taught by a visiting prof from the University of Edinborough, I think Donald Mickie but I may have the name confused.

Like APL, POP-2 had the same associativity for all operators.  Unlike APL, the designers decided that the majority should win so assignment would be left-associative like everything else -- rather than APL's rule that all the other operators are right-associative like assignment.  So you'd end up with statements like:

	n + 1 -> n
