is there `import arrow.core.memoize` for `suspend fun`?

oooh I see, only pure functions. thanks for the instant response :smile:

Would it not be valid to memoise a pure function that happens to use `suspend` to do its work on `<http://Dispatchers.IO|Dispatchers.IO>` though? or is it the case that for such a function, one should perhaps separate it into 2 functions, one pure and one `suspend` with the latter calling a memoised version of the former and doing `withContext(<http://Dispatchers.IO|Dispatchers.IO>)`?

Yes, that would be the general pattern since _dispatching_ is also considered an impure operation in FP. In practice I am curious if these function really provide any value though which is my original answer to the question was also to be use a proper `Cache` abstraction. I've never used `memoise` in Kotlin.
