Diagnostic AL0192 incorrectly reported when using Cookie.Name(...) or Cookie.Value(...) as setters

1. Describe the bug

Using Cookie.Name([Name: Text]): Text or Cookie.Value([Value: Text]): Text as a setter (using parentheses) incorrectly triggers diagnostic AL0192:

The return value must be used for the method 'Name'

According to the method signature and tooltip, passing a Text argument sets the corresponding property of the Cookie. The same setter-style syntax is supported by both Name and Value.

For example:

MyCookie.Name('dummyname');
MyCookie.Value('dummyvalue');

Both statements currently trigger AL0192 because their return values are not used, even though the methods are intentionally being called as setters.

2. To Reproduce

local procedure SetCookieData()
var
    MyCookie: Cookie;
begin
    MyCookie.Name('dummyname'); // AL0192: The return value must be used for the method 'Name'
    MyCookie.Value('dummyvalue'); // AL0192: The return value must be used for the method 'Value'
end;

3. Expected behavior

AL0192 should not be reported when Cookie.Name(...) or Cookie.Value(...) is called with an argument and therefore used as a setter.

This should behave similarly to functions such as CurrPage.Caption, which can be assigned either using direct assignment:

CurrPage.Caption := 'Test';

or by using the setter syntax:

CurrPage.Caption('Test');

Calling Cookie.Name('test') or Cookie.Value('test') should therefore be considered a valid setter call without requiring the returned value to be consumed.

4. Actual behavior

AL0192 is reported for both setter calls:

Final Checklist

Please remember to do the following:

• Search the issue repository to ensure you are reporting a new issue
• Reproduce the issue after disabling all extensions except the AL Language extension
• Simplify your code around the issue to better isolate the problem

Internal work item: AB#649119

Start with the AL0192 diagnostic handling and reproduce the issue using the provided SetCookieData procedure. Check how Cookie.Name(...) and Cookie.Value(...) calls with arguments are classified, then add or update regression coverage so setter calls no longer report AL0192 while value-returning calls still require their results to be used.
