I'm just learning Crystal and was reading a lot about the language. Coming from Ruby, I'm trying out some things that I was used to before, e.g., one-line loops:

x += 1 until x === 5

However, this is seemingly not supported by Crystal, is it?

In src/utils.cr:30:15 30 | x += 1 until x === 5 ^ Error: trailing `until` is not supported

Is it possible to do one-line loops in Crystal?
