Summary of Problem
[splitting this apart from #18849 since chomp() may be a stumbling block all three of those requests going through, and since I have a future filed for this one already...]
While working with strings, I was disappointed to find that they didn't support a .contains() method that would do a substring search and simply return true/false. While find() can be used, the need to compare against -1 makes it feel slightly clunkier for simple "true/false" tests where the location doesn't matter. This issue proposes adding a string.contains() for such cases, which would make it similar to some of our other types that support .contains() like domains, ranges, lists, maps, sets, and other collections.
