Is it possible to assign one array to another directly if their sizes differ?

In Go, arrays have a fixed size, which is part of their type. Assigning one array to another is only possible if they are of the same type, i.e., same size and element type.

For example:

var a [3]int
var b [3]int
b = a // allowed

var c [4]int
// c = a // compile error: different array sizes

If sizes differ, direct assignment is impossible, and you need to use slices or copy elements manually.
