I still think the main problem is non-intended assignment to globals,

declaration to assign to globals would force programmers to consider
whether they really want a global variable.
One possible downside of this is that this very simple Lua program:
a = "Hello World"
print(a)
becomes:
global a = "Hello World"
print(a)
(or "local a..."). Does this make Lua harder to learn?
