I think I was confused because intersperse doesn't seem like a short name to me :) But of course you mean 'prime namespace real estate', which is partly about length but also about being an english word and so easier to remember.[1]
intersperse still seems weirder than map, because map just returns the type of its args, while intersperse is checking the type of elements inside its list arg.
[1] This made me also focus on the fact that testify is actually an english word - and arc is misusing it.

Yeah, that's one reason I'm not sure I agree with this proposal. Fundamentally, I don't like the idea that (intersperse x (list a b c)) would return (list a x b x c) sometimes and (+ a x b x c) others.
If "string:intersperse" is common enough to be a standalone utility with a shorter name, I'd probably name it after PHP's implode(). I'd probably make it use '+ too, so that it could be used to construct lists and custom types of sequence:
(def implode (first between seq)
(apply + first (intersperse between seq)))
(implode "?" '& ...)
(implode "" "\n" ...)
Using '+ instead of hardcoding 'string makes less sense if you have '+ dispatch on the type of the last argument. But hey, I'm a fan of dispatching on the first arg anyway. ;)

How about 'checkify? ^_^ I don't actually mind word misuse, but I do kinda like the idea of reserving the term "test" for unit tests, and I suppose there are even contexts where 'testify could be used for its English meaning:
- assertions
- debugger interaction
- proofs
- simulations of belief, knowledge, perception, persuasion, etc.
- generally, status reports, contracts, and sanity checks registered
with some surrounding framework or compiler
