Syntactic sugar: Any things in B4X?

Based on these answers that explain what is syntactic sugar, what do you think about that? I personally love (in c#) var and ? and i think that can be a great thing in b4x

I personally do not like inline the ? condition. I see that a lot in JavaScript and it can get messy very quickly.

Anyways, this how Erel solved it:

Sub IIF(condition As Boolean, TrueValue As Object, FalseValue As Object)
 If condition Then return TrueValue Else Return FalseValue
End Sub 
'Example
y = IIF(x > 100, 10, x + 10)

It's not the same thing. ? operator check if the condition is true. If yes, it evaluates and return the true statement. If not, it evaluates and return false statement. Sub iif instead, evaluates true and false parameters at same time, so if you have a null value in one of the parameter, you will get an Null exception. This mean that you cannot use iif to check if an object is null, and if it has a value then return it.
A small example of what i mean in c#

           List<string> lll = null;
            Debug.WriteLine((lll == null) ? "null" : lll[0]);
            Debug.WriteLine(Iff(lll==null, "null", lll[0]));

private string Iff(bool cond, object trueres, object falseres )
        {
            if (cond) return trueres.ToString();
            else falseres.ToString();
            return "";
        }

In first line you will get "null", in second line you get an error

Yep, pretty much! I've raised this issue before. Please follow this link:

Nice @wonder, many thanks, i never saw this post. I discovered it by checking a map.
