Extension Methods On Nil Objects

So other language frameworks support extension methods that work even when the object is null/nil.

Xojo doesn’t seem to support this. Is this a bug? A short-coming of the language? Can this be fixed?

For example in C#

public static IEnumerable<TSource> EmptyIfNull<TSource>(this IEnumerable<TSource> source) { return source ?? new TSource[] {}; }

Since XOJO doesn’t have built in Object wrappers for the primitives
Because of this I have created nullable versions of the primitives:

For example I have a class called NullableInteger, but the problem is that you constantly have to null check them

if someObject.NullableIntProperty != null && someObject.NullableIntProperty.Value > 0 then...

This could be completely avoided if extension methods could be called with a Nil input parameter like other languages.
This code be simplified to:

if someObject.NullableIntProperty.Value > 0 then...

And if Operator_Convert supported a Nil input parameter as well, then it could be as simple as

if someObject.NullableIntProperty > 0 then...

I asked for that 4 years ago: feedback://showreport?report_id=31205
