Description

Currently I would have to write code like this (in the Groovy Console) to be safe:

def json = [
    messages: [
        [message: 'test']
    ],
    errors: null
]


[
    *(json.messages ? json.messages*.message : []),
    *(json.errors ? json.errors*.message : [])
].join('\n')

I would like to request for an operator like ?*. so I can write something like this:

[
    *(json.messages?*.message ?: []),
    *(json.errors?*.message ?: [])
].join('\n')

Not sure if it can be simplified further, but that's the idea.
