speculative still has its use, e.g. in https://borkdude.github.io/re-find.web/ I think even with a malli speculative, instrumenting core would just be way too slow and probably not worth it

oh cool! I didn't realize you were using it for re-find, I thought you were using something like grasp.

a good test case would be advent of code puzzles. at one point I had a solution which took 15 minutes with instrumentation and 50ms without or so

(exact number I don't remember but it was something absurd like that)

yeah, it's debatable if it would be worth it, but malli is pretty dang fast comparatively: 40ns vs 450ns for simple schemas. 10x speed increase is sharp

10x won't really solve that problem imo

the problem is that some core functions will become 1000x slower

but exact benchmarks must be done to revalidate that, it's been a while

there's a malli.core/schema? that looks promising

Looks like that checks to see if it’s an instance of a schema, which would force me to invoke (schema) on the data. I’ve been on the fence on how proactive I should be about doing that. I do see there is (form) which does get the data back… I was expecting that there was a schema schema somewhere though.

ah I see

I've just wrapped (malli.core/schema <args>) in a try catch - catch branch returns false to determine if a valid schema is passed in
