So would many of us. But there are problems, e.g. do you have to declare
all globals inside every function? Every block? In particular, what about
global functions you call? Then there's backwards compatibility to worry
If you have to declare all variables, it's rather easier. Alternatively,
see my proposal on lua-users.org.
