I programed in APL! Sure, I just had to change an already developed code from my MSc adviser. It was weird! First of all, you needed an special keyboard just to use it: http://ageinghacker.net/hacks/apl-keyboard/apl-keyboard-1.jp...

When you were not fluent, the myriad different symbols would overload your working memory, making it very hard to program. Just needing to find the symbols in the keyboard would make you program slowly. It had some nice ideas about matrix programming, probably they are similar of pandas or tidy verse. Cool, but the steeeeep learning were really terrible.

Read the article! Great reminiscences from one of greatest computer science elders. Made me understand better the language.
