Alternatively, 'global' could be redefined to mean
what we're thinking of for 'outer'. Then there would
be no change in keywordage.
There would be potential for breaking code, but I
suspect the actual amount of breakage would be
small, since there would have to be 3 scopes
involved, with something in the middle one
shadowing a global that was referenced in the
inner one with a global statement.
Given the rarity of global statement usage to begin
with, I'd say that narrows things down to something
well within the range of acceptable breakage in 3.0.
