let's assume this class:

this()

ref S value() { return m_s; }
ref S value(ref S s)
{
return m_s = s;
}
}
and I do something like this:
auto s1 = S(40);
auto c = new C();
c.value = s1;
s1.n = 80;
give that value has ref in its signature, the s1 is passed as a
"pointer" right?
right
also, when I do: m_s = s; m_s is a copy of s1 or a reference to
it?
a copy
setting s1.n to 80 in the next line doesn't seem to change
c.value so it seems it passed s1 as a pointer but when it comes
to assignment a copy was made?
You got it.
If you want the pointer, you can get it taking the address of s:
`S* p = &s;`.
