If anyone is interested in APL, I would recommend trying out kdb+/q. The personal version is free (no charge): https://kx.com/connect-with-us/download/ https://kx.com/connect-with-us/download/ It integrates an APL-like language (q) with a very nice time-series database (kdb+). Q programmers are highly prized on Wall St and can pull in truly staggering salaries.
