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

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.
