So I wrote a simple ref counted string type because using the built in

strings to implicitly convert to my custom string type?
No, D does not support such implicit conversions.
struct rstring {...}
void fun(rstring s) {...}
...
fun("hello world"); // Currently an error
Would be super nice if it would just call the opAssign when trying to
call fun but I suppose that has some non-obvious problems for why it
does not work that way.
The only way is to be explicit. Three common options:
fun(rstring("hello world"));
fun("hello world".to!rstring);
fun(cast(rstring)"hello world");
Relatedly, user defined types can provide implicit conversions through
'alias this' but unfortunately, current implementation supports only one
such operator.
