### Iterators

The new [iter] package provides the basic definitions for working with
user-defined iterators.

The [slices] package adds several functions that work with iterators:
- [All](/pkg/slices#All) returns an iterator over slice indexes and values.
- [Values](/pkg/slices#Values) returns an iterator over slice elements.
- [Backward](/pkg/slices#Backward) returns an iterator that loops over
  a slice backward.

Package atomic provides atomic operations, independent of sync/atomic,

On most platforms, the compiler is aware of the functions defined
in this package, and they're replaced with platform-specific intrinsics.
On other platforms, generic implementations are made available.
