I think this would be fixed if
https://github.com/dlang/dmd/pull/11273 gets merged.
The feature still needs some work. With this PR aliases of
members only works when they are declared in a function scope and
not in the aggregate scope.
Example:
---
struct Inner
{
int a;
}
struct TopLevel
{
Inner inner;
alias ia = inner.a;
}
void main()
{
TopLevel tl;
alias ia = tl.inner.a;
ia = 42; // OK with PR 11273
tl.ia = 42; // NG Error: need `this` for `a` of type `int`
}
---
I think it's not good to merge until the second case works.
Also it requires approval. For now it is specified that
expressions cant be aliased.
