Sorry, I wasn't clear.

*If* "function f(...)" was sugar for "global f = function(...)" then the global checking wouldn't work on functions.  That might be a nice feature in the top level scope, but it would not be a nice feature in any nested scope.  (I'm shooting down my own suggestion)

strict.lua does not check assignments to globals at the top level.  I share your understanding of global - it checks all nested scopes.
