Checklist before submitting a bug report

• I have reviewed CONTRIBUTING.md document
• I have done a quick search on the issue tracker to check if the bug report is not redundant

Context

Based on the "Kernel Modeling Language Version 1.0 Beta 2.6" chapter "7.4.9.4 Base Expressions" the instantiation of classes should be possible. But the example provided there shows errors in the SysIDE.

Note: Syntax has changed and now uses the "new" keyword: ... new Member(...) based on spec "Kernel Modeling Language Version 1.0 Beta 3"

Steps to reproduce the bug

Add the following to the editor:

private import ScalarValues::*;

class Member {
    feature firstName : String;
    feature lastName : String;
    feature memberNumber : Integer;
    feature sponsor : Member [0..1];
}
feature thisMember = Member("Jane", "Doe", 1234, null);
feature nextMember = Member(
    firstName = "John",
    lastName = "Doe",
    sponsor = thisMember,
    memberNumber = thisMember.memberNumber + 1
);

Current result

Error reported:

Expected result

No errors.
