Aside from the fact that the compiler would have to know _all_
globals (which would require an include statement!), what about
these examples?
global x -- make a global x
y=1
function foo()
x=a -- what is x, what is a?
y=a -- what is y?
a=a -- what's this?
a=a -- and now?
b=1 -- and this?
if ... then
b=1 -- new b or same as above?
b=b+1 -- and here?
end
for b=1,10 do ... end -- new b or same as above?
for c=1,10 do -- again, new c?
...=function() print(c) end -- will all funcs get the same c?
c=c -- what gives this?
...=function() print(c) end -- and now?
d=c
...=function() print(d) end -- and now?
end
end
You will get really strange results with block scope and other
strange results with a single function scope.
