This follows the naming convention from the stdlib packages "slices" and
"maps" of using the verb "Collect" to represent gathering the items from
a sequence into some sort of collection data structure.

We were previously using this module to access the then-experimental
"slices" package, but equivalent functionality is now available in a
standard library package so we no longer need to use the experimental
version.
This remains as an indirect dependency just because some of the tools we
use depend on it.
