Methods for get an Array of values or View of a IntSet or Set

[diegozea]

There isn't a values() method for IntSet and Set

[diegozea]

For Set an easy implementation would be:

values(set::Set) = keys(set.hash)

A "view" of the values in a set is the set itself. If you want an array of the values, use collect(s).

Thanks Jeff, I was looking for collect()
Isn't not documented on Set-like but is in Associative Collections
values() sound more intuitive to me, but collect() is fine.

After #2347 it might make sense to define values(s::Set) = s.
