This is OK as long as f is *strong* pure. D pure is not the

And GC.malloc is not strong pure, as it returns mutable data.
Ah, this is the piece I was missing. I was aware of weak/strong
pure, but I didn't know the return type plays a role in that.
Could core.stdc.stdlib.malloc and friends also be marked pure
then?
No.
Allocating on the GC is "stateless" as the GC will handle the
state by itself, from the program perspective, there is no state
to maintain.
malloc require free, and the state management is pushed on the
application rather than the runtime. It is not pure.
