--- Comment #1 from ag0aep6g@gmail.com ---
You have to mark the constructor as `pure`:

    struct S { this(ref int val) pure { ++val; } }

Attributes are only inferred under special circumstances. You generally have to be explicit with them. Closing as invalid. Please reopen if I'm missing the point.

Yes, thanks. What I was confused by was actually when the struct is defined inside the unittest with the static keyword - pure is not inferred. Non-static nested struct inference works, it seemed weird that adding static prevents inference. But obviously the compiler treats it the same as the code in comment 0.
