"Big Questions Mnotation" The retcon is that it's not "APL"+1, but "APL"+Fibonacci.

'Mnemonic' almost makes sense, you could even leave it as BQN and claim the m is silent.

  Python: "".join(chr(ord(c)+1) for c in "APL") → 'BQM'

    The comment you're replying to is the BQN code that adds a Fibonacci number to each letter of the "APL" string. You're python code is spelled just "APL"+1 in BQN. Array languages implicitly so a "foreach" when there is a scalar operand

        APL doesn't do this character arithmetic; BQN does. But it's not weak typing, it's an intentionally designed feature[0]; so things like "a"+1.2 or "a"+"b" error. It's quite useful too - you can add the null character to a number (or list of numbers) to convert code points to respective characters (or subtract to do the inverse). Or do things like '0'+x to convert a list of numbers to a string of digits (and x-'0' for the inverse); or 'a'+↕26 (↕26 being a list of the numbers 0…25) to generate the alphabet. (it's the same logic that's behind any language with pointers - you can add a number to a pointer, subtract a number from a pointer, and subtract two pointers to get a number) [0]: https://mlochbaum.github.io/BQN/doc/arithmetic.html#character-arithmetic https://mlochbaum.github.io/BQN/doc/arithmetic.html#characte...

        Well said. Your average "very weakly" typed language will happily do "APL"+1 == "APL1"
