If an aggregate member is pure but not scope when can it escape the

Only via return?
I'm not sure if returning the `this` pointer is considered escaping it.
The caller already had access to it. Under the hood, the `this` pointer
is just another argument passed to the function.
In the struct and class case?
A nested class seems to be able to escape the `this` reference:
class Foo
{
Bar b;
class Bar
{
void bar() pure
{
b = this;
}
}
}
