SNOBOL should be looked at, if for nothing else, for its string handling (add a brief look at Icon right afterwards). I would have killed to take APL in college, but despite having to program on an IBM 370 mainframe, no classes were offered. I'm still a little ticked.

It's never too late to start playing with APL. I started around the time GNU APL was released (a few years ago), and I'm having fun with it.

I also ended up writing the Emacs integration for it. Please give it a try.

I have over the years played with it, but I was rather annoyed that having to put up with all the disadvantages of using an IBM 370 that we didn't get some advantages.

There's a nice overview of APL here: http://www.zerobugsandprogramfaster.net/essays/5b.html
