Pascal, Interesting ideas on arrayfire args.
I will probably resist the idea of making dop verbs dyadic. I think it better to stick closer to the arrayfire syntax. But it makes sense to avoid unnecessary boxing. af_add_jaf_ afad;afbd NB. works af_add_jaf_ afad,afbd NB. fails, but probably should work On Wed, Jan 26, 2022 at 10:03 AM 'Pascal Jasmin' via Programming < programm...@jsoftware.com> wrote: > An interface suggestion would be to transform all verbs that currently > take 2 boxed arguments into unboxed dyad arguments. > > this can be done by adding the adverb (@:;) for the dop class verbs. and > (@:;~) for the reduce class verbs such that the operating axis is the x > term.
