What's the idiomatic way to join an array into a string?

Question

Many languages support constructs like the following (Python, in this case):

>>> ["One", "two", "three"].join(" and ")
"One and two and three"

In Crystal, what is the idiomatic way to do this?

Oh, duh. Here I go again, not finding the right things in the docs (Google sure didn't help). Part of `Enumerable` and not `Array`, huh. — obskyr, Mar 14 '18 at 09:56
...I just realized it'd actually be `' and '.join(["One", "two", "three"])` in Python, but hey. — obskyr, Mar 14 '18 at 16:06

Use #join, which Array inherits from Enumerable. The example in the question works just as well in Crystal.
