I only wrote this snippet because I have multiple resources that are using the same code, and I don't find it cool to repeat the same code over and over again.
Besides, a powers of 2 list is always useful.

* - This resource functions as a repository
* for values and code that has been, is and
* most likely will be repeated by a lot of
* coders. It is a list of all powers of 2.

* constant function GetPowerOfTwo takes integer x returns integer
* - This returns 2^x.
* - If x = 31, this function will return 2^31 - 1.
* 2^31 cannot be represented in a 32-bit signed integer.
