As everyone has found at some stage, you can have a terminology conflict if the editor you are using defines an AppleScript term. The word "language" is an example: you can't use it as variable name in Script Editor because it's in SE's dictionary.
A similar thing can happen with classes. Developers can extend classes by adding extra methods, using things called categories and class extensions. They are very common because of the convenience they offer. And once they have been loaded by the application, their methods are all accessible to ASObjC code hosted by the app.
The arrayByRemovingObject: method is a fairly classic example, simplifying a common job.
I suppose the removal of empty arrays would have to be something like
this:
-- Lose any empty arrays and coerce to list.
set nonEmptyArrayPredicate to current application's class "NSPredicate"'s predicateWithFormat:("self != {}")
set phoneNumbers to (phoneNumbers's filteredArrayUsingPredicate:(nonEmptyArrayPredicate)) as list
The ASObjC equivalent of what SD is doing would be:
set phoneNumbers to phoneNumbers's mutableCopy() phoneNumbers's removeObject:{} -- and then set phoneNumbers to phoneNumbers as list
