Say I have a variable x, and I want to check if it's equal to any one of multiple values a, b, c, d, e (I mean the == equality, not identity).
In an SQL query the same concept is handled with
WHERE x IN (a, b, c, d, e).
Is there something equivalent in Scala that's as straightforward as that? I know it's otherwise possible to do it in one line with a complex expression such as building a HashSet and checking for existence in the set, but I'd prefer to use a simple construct if it's available.
