27 Ιουλ 2013 · from the reference doc : (tour.golang.org) Inside a function, the := short assignment statement can be used in place of a var declaration with implicit type. Outside a function, every construct begins with a keyword (var, func, and so on) and the := construct is not available.
Golang does not allow pointer-arithmetic (arrays do not decay to pointers) and insecure casting. All downcasts will be checked using the runtime-type of the variable and either panic or return false as second return-value when the instance is of the wrong type, depending on whether you actually take the second return type or not.

No one reinvents stuff thats done already unless you can do better or need something specific to your program, if you inspect the code and see it does it well why bother do it yourself - not only do you waste development time and cost, you are also potentially going to bring in bugs or simply wrong implementations if you don't know completely what you ...
@Arijoon, ^ means invert bits in the expression so if: uint(0) == 0000...0000 (exactly 32 or 64 zero bits depending on build target architecture) then ^unit(0) == 1111...1111 which gives us the maximum value for the unsigned integer (all ones).
