Shouldn't these `Compiled` statements should be in a companion object instead of the class itself?

Here it's a bit misleading I think, as we don't want it to be run more than once, even if we would instantiate several `WorldsTableQuery`.

(I'm saying that for people that may be interested in looking at the benchmark code and copy code from it. I saw that the `WorldsTableQuery` is only instantiated once here)
