Comparables::checkBoundsValidity, which is used by Comparables::assertIsBetween, does build an error message String even if the assertion does not fail. This results in noticeable overhead. The JVM can hardly eliminate the String building since `start.toString()`, `operator.toString()` and `end.toString()` may have side effects. This commit moves the String building inside a `Supplier<String>` which is only evaluated on failure.
