Null Or Default Construct?

[Ashiq A.]

Hi,

In languages like C# and Javascript, I can write code like:

var c:SomeObject = ...

var x:name = c.name || "Unnamed"

If c.name is non-null, I get the value from c.name; if it is null, I get the value "Unnamed"

Is it possible to write a similar construct in Haxe? 

This is not the same as an optional function argument, which is all I could find in the docs.

I think we would all like a `??` operator like in C#. Haxe type system however wouldn't allow `||`.

Either syntax is cool as far as I'm concerned.  Right now, I have to write:

var x:String = c.name != null ? c.name : "Unnamed";

If I have to do this several times, it gets tedious; much easier to write:

var x:String = c.name || "Unnamed";

var x:String = c.name ?? "Unnamed";

It sounds like I'm not the first person to ask for this, and that there is (sadly) no way to do this yet. Is there a macro I can use for this or a library, or something that'll give me shorter syntax than the ternary operator?
