Hi

I’m writing a physics system and need fast math access. I have run some speed tests on private functions and public static functions. The result defiantly shows that private is a lot faster, therefore i wanted if you could point at the e.g. Math.sqrt function, from a private function:

```auto
private function fastSqrt = Math.sqrt

```

Is there anyway something like this could be obtained?

Thanks in advance!
