Early break of iterations

Questions
1

What is the way to get out of an iteration, based on some condition before the whole collection is iterated over (and probably also return something from the iteration at the break time). Example:

(
// I know do returns 10, but for lack of knowledge and to convey the purpose...
10.do {
	arg x;
	if (
		(x == 5),
		// Here I want to return the x, and break the iteration so
                // that the result of my iteration is 5
	)
}
)

It’s a bit funny syntax, but:

(
block { |break|
    10.do {
        arg x;
        if (x == 5) {
            break.(x)
        }
    }
}
)

Within a method, you can use the method-return token ^ but in interactive code, it has to be this way.
