@PyGamer0 because there was no complex support in k5 and k6

@PyGamer0 the original k is not unicode-aware. in ngn/k you can use codepoints greater than 127 as single-character user-defined verbs - they can be used infix. their definition requires parentheses, e.g.: (⌽):,/|0 1_

this was a simplification. maybe temporary. i know some unicode chars are letters and they should stick together to form identifiers..

@ngn the short-lived k9 (pre shakti) had single char unicode functions. don't remember if there was any way to define new ones.

e.g. I remember it used the square root unicode char for root.

wasn't that k7? it had pi and a slashed o (π ø Ø) and maybe more stuff

maybe k7. the one that was distributed through conda.

@ngn ..actually that should be (⌽):{,/|(0,x)_y}. the monadic form requires a colon: (⌽:):{|x}

if unicode wasn't such a mess, and if there was a simple way to tell apart letters from non-letters (and possibly somehow verbs from adverbs), i'd have used it..
