I can't resist a more verbose, but more functional way:

[1,2].identity { assert size() == 2 } .every { it instanceof Integer }

@dinko yeah, that's why I choose to do my example with listVariable*.getClass()

It would in this particular example, but this may be dangerous for
some other cases. Try e.g. this:

[1, [:], [class: 1]]*.class
