Kapps:
That code is not @nogc safe, as you're creating a dynamic array within it. The fact that LDC2 at full optimizations doesn't actually allocate is simply an optimization and does not affect the design of the code.
Walter has answered to another person:
The @nogc will tell you if it will allocate on the gc or not, on a case by case basis, and you can use easy workarounds as necessary.
That can be read as the opposite of what you say. The DIP60 needs to contain a clear answer on this point.
