is it unavoidable to have separate spec/alt and spec/or? why can't we use spec/or as regex op?

same with spec/& and spec/and

same with spec/keys* and spec/keys

there is already a way to escape "regex context" by using spec/spec, it would be nice to have slimmer api..

hmm, actually, both spec/or and spec/alt work in regex context

They are not the same in a regex context

If you have another regex underneath the alt it can combine with regexes above in ways that or cannot

So yes, they are both needed

ah, I see

it just feels they could be semantically the same

they are semantically different

just as s/coll-of and s/* are semantically different

and s/and / s/&

what is the difference in their semantics?

regexes combine to describe the structure of a single collection. non-regexes do not.

it feels like with regexes and s/spec "escaping" there is no need in coll-of/and/or?

you can express the same things

no?

specs are intended to express meaning to the reader and these have different meanings

whether you can turn the crank on two things and get the same answer is to some degree beside the point

I think I understand

they are completely different implementations and likely have very different perf characteristics in validation

also need to consider generation, etc

yeah, right
