Hi, so if you have this piece of code:
struct C {
void f() {
string[] others;
const string[] restArgs;
foreach (i, arg; args) {
if (isValidArg(arg)) {
restArgs = args[i + 1 .. $];
break;
}
others ~= arg;
}
// "others" is a list of args before the valid arg is
encountered
// "restArgs" is a list that is the args after the valid
arg
}
}
Is there anyway to set a const object after declaring it in
the above context?

It looks like there is a Rebindable type for that in
std.typecons :
https://dlang.org/phobos/std_typecons.html#Rebindable
Guess I could do that. But would there be a difference if I just
declared the restArgs as non const then? Given the objective is
"set this var to point to this thing and not allow it to be set
to point to anything else".
