Description

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())
