@Adnan 2-byte builtin request: .N: will return 1 (truthy) if it's the last iteration of the loop/map/filter/etc., 0 (falsey) if it's not the last iteration. Thought about it after seeing @Emigna's answer here just yet.

Alright, here's a grab-bag of feature suggestions for @Adnan:

* The big one: change `õ` to a variable that defaults to `""`, and have a single-byte command (`ñ`?) to append to it. This way, we'd have incremental variables for all types: `¾`/`¼` for numbers, `¯`/`ˆ`for arrays, `õ`/`ñ` for strings. (Probably needs two-byte commands to clear or directly assign to it as well).

* I've never wanted suffixes in the order returned by `.s`. A two-byte shortcut for `.sR` (`.η`?) would be nice.

* As far as I can tell, `O` and `P` on lists that contain both numbers and non-numbers do nothing. Ignori…

All very good ideas. I can't say I've ever needed P/O to work on mixed lists, but I can't see a drawback to them having this function. The suggestion for à/ß might need some consideration as they could no longer be used to pop the largest digit in a number. Doing Ws\ over ß is a bit clunky. Haven't personally used ß a lot though, but I've seen it used by others more.

Grimy

Yeah, the change to à/ß would not be retro-compatible. I haven't seen any answer that would break because of it, but it's a good idea to be careful.

As an alternative, a two-byte max(a, b) would also be cool (we already have a two-byte min(a,b), it's ÅL).

Emigna

‚à works as a 2-byte alternative

Grimy

Doesn't vectorize though

Or does it?

Nah it doesn't, just tested it

ÅL does vectorize, otherwise it'd be completely redundant with ‚ß
