Description

I find myself writing a lot of code in the following form:

if(data.field) obj.field = data.field
// Or
obj.field = data.field?: obj.field

It would be nice to have a groovy operator to handle this for me.

obj.field ?= data.field

more like ?:= instead of ?= I would say...

but it does not allign well with other operations normally you have a = a op b and you make a op= b out of it. That means the part I assign to comes first. Now in what you want the order is exaclty the other way around.
