I don't agree. To test a runtime value you need an if statement, and it creates
the scope of its then and else parts, if you remove a variable inside one of
those two scopes, x is present again when the then and else scopes are
finished. So what's the problem?
import std.conv: to;
void main(string[] args) {
int x = 10;
enum int y = 5;
// here x can be used
if (args.length > 1) {
// here x can be used
delete x;
// here x can't be used
float x; // not allowed
} else {
// here x can be used
}
// here x can be used
static if (y < 2)
delete x;
// here x can or can't be used according to the compile-time value of y
}
