Groovy: command chain with dots and multiple assignments

I'm trying to understand why command chaining without dots is not working with multiple assignments. For example this dummy code:

def (one, two) = String.valueOf 12 trim() iterator()

Raises:

Script1.groovy: 2: expecting EOF, found '12' @ line 2, column 33. def (one, two) = String.valueOf 12 trim() iterator()

Of course if I add the dot then everything is fine

This compiles (but does not properly work) with Groovy 3.0.5 - what version are you using? – cfrick Sep 22 '20 at 11:27
I'm using latest version of groovy 2.5 -> 2.5.13 – Faur Ioan-Aurel Sep 22 '20 at 11:47
what are you trying to do? – injecteer Sep 22 '20 at 16:12
I'm just trying to implement a nice DSL, last chained method returning a list of two maybe three objects. I want clients/consumers of that DSL to be able to nicely "unpack" the list using multiple assignments. – Faur Ioan-Aurel Sep 23 '20 at 08:47
`def (one, two) = String.valueOf 12 trim()` works for me in groovy 3.0.7, also works in 3.0.5, and `def (one, two) = String.valueOf(12).trim()` works in 2.5.9 – smac89 Mar 08 '21 at 03:54
