Two questions:
1. What does this mean and why is it needed?
line 95: alias array this;
This means that `array` can be used instead of `this`
Hmm should not that change the meaning of this throughout the struct? is
this good practice?
No, it's simply a fallback. If the symbol doesn't work with this.symbol,
try this.array.symbol.
It's D's version of implicit conversion.
You can make the alias this a no-arg function and it will try calling
that function.
