a.b.c = d;
If b is anything that has a struct type, and c is anything else, the

struct S

Why should this not be allowed?
Because in the general case it might not work.
It's simple: if you disallow it, no bugs caused because of this can
exist. If you don't disallow it, sometimes it might work, sometimes it
won't work. Which option do you prefer as a programmer?
