Yeah, I wonder if that is 425k _formatted_ lines of APL? I'm blanking: wasn't there someone who wrote their hedge fund's entire data processing pipeline in 4 lines of APL?

Characters maybe?

Most "production" APL is pretty verbose. See https://github.com/Dyalog/Jarvis/blob/master/Source/Jarvis.d... for example

Among Us comment char.

Some of this seems readable to me (someone who's never seen APL before), but some of this is just wild:

→0⍴⍨0∊⍴i←⍸127<c←⎕UCS w

But to me as a relatively experienced APLer, it reads very clearly as "return if there are no non-ASCII chars in `w`" (and if there are, the indices of those chars will be stored in `i` and the code point of every char will be stored in `c`).
