[VOTE] new operator ?=
Hi all,
If the new operator ?= (e.g. a ?= 'foo' is equivalent of a = a ?:
'foo') were to be added to Groovy programming language, do you like it?
(Yes: +1; No: -1; Not bad: 0)
Cheers,
Daniel.Sun

What goes up, must come down. Ask any system administrator.
There are 10 types of people in the world: Those who understand binary, and
those who don't.
To understand recursion, we must first understand recursion.

Re: [VOTE] new operator ?=

For all our other operators of the form:
a X= b
it is shorthand for:
a = a X b
So, to follow that convention the operator is:
a ?:= b
which as per previous discussions is a bit cumbersome, so I am +1 for
the shortened form so long as we document appropriately.

RE: [VOTE] new operator ?=
Posted by "Winnebeck, Jason" <Ja...@windstream.com>.
At first I was going to vote 0, because I feel like a = a ?: b is clear (and I compare it to a = a || b from JS). However, looking at the dev list, I definitely see a nice case for it:
person.name.last = person.name.last ?: "unknown"
When you have a non-trivial assignment expression, I see the benefit:
person.name.last ?= "unknown"
However, I feel like it is not intuitive or clear. But, I don't think the operator hurts, and it's certainly not any less intuitive than <=> for example or even ?: when seen for the very first time. It's an easy look up in Groovy docs, and if you don't know it and don't use it, it's not a huge loss. So it doesn't hurt to add it, and while not instantly readable, it's a trivial docs lookup when someone is reading the code.
So, I vote +1. But, honestly, I don't see myself using it very often as I'd normally use Elvis at time of initial assignment. I wouldn't put it very high on a prioritized backlog of things to improve for Groovy.
