If you could make any changes to D, what would they look like?

But the thing is, lowerings don't *have* to be implemented as AST
mutations. They can be a side-branch of the AST node for example. Or
just translate to pure IR along with the rest of the code, then
transformed as IR without touching the AST. It's more efficient (and
less bug-prone) to transform IR than to meddle with the AST anyway.
