Concatenating two arrays

[cbeck88]

It would be really nice if there was a syntax like

join(arr1, arr2)

that produced a new array of the correct length, if both input arrays have the same type.

Doing it manually with copy_from_slice is less readable, and copy_from_slice can panic if you do it wrong, so it would be nice if there is a simpler API that doesn't panic in any scenario.
