Would it make sense for =': to be given the first item as the initial value as a special case? Would be useful for checking if all elements are the same

@copy doesn't it already work that way? ngn.codeberg.page/k/#eJxTSlSyVbdSSkxKVgIADw4Crg==

copy

I was thinking something like this (unless you know a shorter idiom): ngn.codeberg.page/k/#eJxT01eIsVW3MjRQNgAADQQCJA==

ngn

so you want the default left arg to be first of the right arg

copy

Yes, like &': (at least in ok: github.com/JohnEarnest/ok/blob/gh-pages/docs/…)

ngn

some arithmetic operations such as + * & | have an identity elements - it's easy to choose a default left arg for them

but = doesn't have such an identity element, it defaults to a null like 0N, or " ", etc

@copy what if you're looking for doubled characters in a string. wouldn't you be surprised if the first one comes out as doubled?

copy

Ah, right

Good point

K (programming language)

K is a proprietary array processing programming language developed by Arthur Whitney and commercialized by Kx Systems. The language serves as the foundation for kdb+, an in-memory, column-based database, and other related financial products. The language, originally developed in 1993, is a variant of APL and contains elements of Scheme. Advocates of the language emphasize its speed, facility in handling arrays, and expressive syntax. == History == Before developing K, Arthur Whitney had worked extensively with APL, first at I. P. Sharp Associates alongside Ken Iverson and Roger Hui, and later at...
