Arthur Whitney is a Canadian computer scientist most notable for developing 
three programming languages inspired by APL: A+, K, and Q and for cofounding 
the U.S. company Kx Systems…

A+ is free software and available in the debian repos
Last I knew the proprietary K,Q cost $ 25,000 per seat (!!)
Above may explain at least partly why people are willing to pay so much for the

On the more syntactic side I happen to hold more fringe views:

Some few more things do work in haskell:

Bottom Line: APL's character set was ‘exotic’ in its day
