It's ten times easier to write code that way, than the way Manu
complained about in the OP.
To clarify:
1) If `scope` were implemented, Manu's example would look like
this:
// Declaration
void func(in CustomString s1, in CustomString s2);
// Whenever rvalues need to be passed:
func("hello", "world");
2) With my PR, it looks like this:
// Declaration
private void funcImpl(ref const(CustomString) s1, ref
const(CustomString) s2);
mixin acceptRVals!("func", funcImpl);
// Whenever rvalues need to be passed:
func("hello", "world");
3) Currently, we have this:
// Declaration
void func(ref const(CustomString) s1, ref const(CustomString)
s2);
// Whenever rvalues need to be passed;
auto temp1 = "hello";
auto temp2 = "world";
func(temp1, temp2);
If A is the number of such functions, B is the number of `ref`
arguments per function, and C is the number of calls where
rvalues should be passed:
(2) Requires A more statements than (1).
(3) Requires B*C more statements than (1).
Obviously there is little reason to complain about any of this
unless B >= 1 and C > A, so unless I'm missing something, my PR
is a large improvement over the status quo.
