I may misunderstand but from his code:

                   --  "checks" is a global, but it's just a dummy in
this case and not used.

"global checks" as a statement doesn't "turn on" global assignment
checking? Global assignment checking would be always on? Or is this
simply how it works at the file chunk level? (Perhaps a new thread
discussing the new change is warranted like the earlier "a new
proposal for environments" thread. It would be most helpful to have an
authoritative description of the proposed design.)
