> Deriving from discussion in GROOVY-5785, it would be nice if there were a way
> to call methods inline which return undesired return values. In the other
> issue, the example was calling removeAll() to find the difference between two
> sets:
> def extra = set1.clone()
> extra.removeAll(set2)
> println extra.size()
> You could use Object#with() here:
> println(set1.clone().with { removeAll(set2); it }.size())
> The inline() method implies "return it" at the end of the closure:
> println(set1.clone().inline { removeAll(set2) }.size())
> It might even make sense to define a new operator rather than a method,
> similar to the safe navigation operator:
> println(set1.clone()&.removeAll(set2).size())
