But this is already the behavior for everything but module declarations:

struct A
    deprecated(""~"") int a;

void main()
    A s;
    s.a = 4;

$ dmd -run test.d

Deprecation: variable test.A.a is deprecated -

Yes, in Phobos we are trying to enforce Phobos style guides via dscanner, and
we need this in order to make every line in Phobos less than 120 characters.
