Re: [go-nuts] [48]byte should be make to empty
Or even just declare the var without any value assignation because it's
zero value is an array of zero byte value, which is 0.
var array [48]byte

Re: [go-nuts] Why not a mixture of value and pointer receiver?
Perhaps There is a handy exception, though.

Thanks for this library, I also found some of those missing features that you listed in the README.
