OK. Attached is another example that is almost like the real code.

Near the top of the file, you will see the Base-Shape type, with some stuff
inside a block comment. Even as it is, with only one type in the union, it
already takes a very long time to process. But as you uncomment more and
more types in that union it becomes really, really slow. I'm afraid you
will not be able to uncomment everything.
