the consequence of this is that global variables are only visible in
included scripts if they require the "include" extension themselves.  I
don't think this natural behaviour, and why I have advocated making
variables global by default.

there is an alternative which may be easier to get consensus for:  the
change of text above, and an extra extension, call it "globals".
"globals" adds the :global modifier for "set" _and_ makes already
declared globals available to the current script.

this means that a script will only be able to use the variables it has
set itself unless it explicitly asks to import the globals.

"globals" can be put in the "include"-document, or in a separate
document.  I favour the former as I think there is a natural connection.
(it could also be in "variables", but that would delay the document
needlessly.)
