I understand motivation to use undefined instruction.
Problem is that compiler create invalid opcode SILENTLY. This technique to enforce run-time error is possible but NEWER without any warning.
For clarification bug isn't UDF instruction itself. It is caused by code. Garbage in, garbage out. Problem is no message about it during compilation.
