Problem overloading operator for a struct with an immutable member

I don't know if this is a bug or expected behaviour. The struct
is mutable, assignable and pre-increment operator works. But
post-increment doesn't compile because of the immutable member.

struct S
{
int i;
immutable(Object) o;
S opUnary(string op)() { return this; }
void opAssign(S other) {}
}
void main()
{
S s, t;
t = s; // OK
++s; // OK
s++; // Error: cannot modify struct s S with immutable members
}
