[jira] [Updated] (GROOVY-8997) Add DGM `then` to transform nested method calls to method call chain

["Daniel Sun (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-8997?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Daniel Sun updated GROOVY-8997:
-------------------------------
    Description: 
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:
{code:java}
// the following code is equal to the above code
a()  |>  b(3, _)  |>  c(_, 2)  // _ represents the former method call result, and |> is like a big arrow representing the direction of data flow
{code}
