[-2, -6, 5].collect { if (it < 0) -it; else it }
returns "[null, null, null]," because the parser considers the last statement to be an "if" statement. Instead, we can propagate the optional return to the if and else clauses, so that the above will return [2, 6, 5].
James feels it should only be done for New Groovy.
