This is a low-priority and low-importance "enhancement suggestion" (it's not even an enhancement request because I am not sure if this is a good idea. I will close it if you think it's a bad idea).

Currently you are allowed to use $ to denote array lengths inside their [],
like this:
arr[$ - 1]

The idea here is to extend the $ syntax as suffix too, something like this:


@property size_t __dollar(T)(in T[] a) pure nothrow {
    return a.length;
}
void main() {
    int[5] a;
    auto len = a.$;
}


This shortens the code, and this code isn't harder to understand because D programmers already know that $ means the length of the array.

I would consider this a bad idea, but that's just me.
