Could the scan variants be unified into a single adverb that tells the verb to preserve intermediate results?

@chrispsn example?

@chrispsn Well, +/ is *|+\ -- in general, f/ is *|f\ ; and if you adopt ktye's and CoSy's "no such thing as atom, only length 1 vector" then each-both (') becomes each-left if you emlist the left side, and each-right if you enlist the right side.

(in general for dyadic f, that is)

@ktye tcc (or the standard it implements) doesn't even like $ as a macro name

@ngn "$" not being a valid name is a part of the C standard afaik

@dzaima there are many c standards

TIL: there's a C18

@ngn i don't think this differs between any of the iso ones

@dzaima oh, i don't claim that. i'm not familiar with any of them :)

question #1: how many useful functions are there which are lambdas in x, y, and z? e.g. {x y z x} is useful (multicolumn sort and converging select)

yep, the latest draft says identifiers are [a-zA-Z0-9_], but notes $ as a common extension

question #2: how many useful short compositions are there? e.g. *|

@StevanApter for #2 @chrispsn ran some statistics on my codegolfing solutions, if that counts as useful

without looking i can think of these: <<: *<: *>: +|: ~= ~< ~> ~^:

@ktye @dzaima $ - deja vu

@ktye should i replace $ with a letter? there are some unused ones: G J M Q(almost) X Y

@ngn it would only help if i can get it to run with tcc, which is not clear if it works at all. maybe there are more preprocessor problems. maybe you can check if you see any issues with those i put under ifdef TINYC. for clzll i don't know the 64bit assembly, so i cast to 32bit.

Y represents the same sound (at least in english) as the "i" in "if" and looks like a branch or a fork in the road

@ktye clang compiles clzll as a lzcntq instruction

that's with -march=native

@ngn so +/\ becomes what's +\ now

TIL fixedpoint over does a different check to fixedpoint scan

Fixedpoint over just checks prior value

fixpoint over should check initial value as well (it took a bit of persuasion to get charlie to make that extension in k4)

@chrispsn looks like j

@ngn huh. There you go
