[:] still has a use for arrays.

Most likely they originally used an array, and changed it to a slice later.
Since that line still compiled, it didn’t get changed. Or else they are just
confused.
Anyway, I can’t think of any reason to use [:] on a slice either.

Slicing is useful but is there a difference between simple slice assignment
and [:] ?
Like this:
A := []int{1, 2, 3}
b := A[:] vs. b := A
Why would I want to use A[:] if A is a slice? If A is an array I would
understand. But it is a slice.
I found this in some third party library and got puz
