APLs are really nice, though! I think they scare away newcomers since they look like brainfuck but it's incredible how you can write fairly intricate programs with one-liners. Also can be incredibly fast since array operations are straightforward to vectorize.

I just wish the K language or KDB+ was open sourced. We'd see people from just about every industry drooling over how nice it is.

With companies like Simcorp, it doesn't sound so odd.
