> Here is a sample to transform nested method calls to method call chain:
> {code:java}
> // nested method calls
> c(
>    b(
>        3, 
>        a()
>    ), 
>    2
> )
> {code}
> {code:java}
> // method call chain
> a().then {
>    b(3, it)
> }. then {
>    c(it, 2)
> }
> {code}
> BTW, I even want to introduce a new syntax, which was discussed in dev mailing list( http://groovy.329449.n5.nabble.com/GEP-Concatenative-Method-Calls-tt5747708.html ):
> {code:java}
> // the following code is equal to the above code
> // _ represents the former method call result, and |> is like a big arrow representing the direction of data flow
> a()  |>  b(3, _)  |>  c(_, 2)  
> {code}
