alias this does that, although it does for all unknown
methods, not specific ones:

struct A {
    int[] data;
    alias data this;
}

A a;

a[0] = 10; // this works like a.data[0] = 10;


alias this also lets you pass the struct
when the member is expected:

void somethingWithArray(int[] arr) {}

A a;
somethingWithArray(a); // works, passes a.data automatically
