No, I haven't sorry. I agree with the other comment in that APL, if it is to go anywhere, needs to be open sourced. I'll go beyond that and say that what we need is a new iteration of APL that addresses all the issues with a language that is now at least 30 years away from its most active and innovative period. That's a tall order. I can see getting into something like that as a retirement project. Way too much other good stuff to do now.
That'd be a nice project. It's not APL, but I wanted to add that Perl6 has some APL features such as letting you define custom operators using any Unicode symbol you like, so you could technically write an APL language on top really easily. I wonder if more APL features will pop up in other languages in the future.
