I don't know what's happening here, but it seems like a bug.
This should not compile (it does for me, despite the comment
above).
Yes, I think it's https://github.com/dlang/dmd/issues/19893. If
`parenthesized` is moved above `main`, I get:
```
Error: cannot take address of expression `parenthesized("2 + 3")`
because it is not an lvalue
string * ptrSum = &parenthesized("2 + 3");
^
```
