You are converging on the Python implicit-local rules.  I think there
are a handful of reasons why the Python rules are unsuitable for Lua,
the main one being that they seem to require a multi-pass compiler to
implement.  (You have to read through an entire function before you
know which names refer to implicit function-scope locals; this matters
when generating bytecode for variable reads.)
