Personally I liked being able to use globals before I learned how
lexical scoping worked. They are definitely easier to use for
beginners, which I think is part of why Lua is easy to learn. I would
advise beginners to give their variables unique names of course.

Though if I "pollute the namespace" with a global called "a" or
"count", it’s only 50% my fault :-)
