Yeah, I read all about weak/string purity and I do understand the

So, to correct myself: As I understood strong purity implies
memoization. Am I correct?
Yes, as long as you don't rely on distinguishing objects by address.
Purity of allocation is frequently assumed by functional languages
because without it it would be difficult to get much work done. Then,
most functional languages make it difficult or impossible to distinguish
values by their address. In D that's easy. A D programmer needs to be
aware of that, and I think that's fine.
