My apologies to Andy and all.
I <thought> I knew what I was talking about.

Here are links to the relevant spec sections...

Responder (i.e. me in this case) RTFM yourself.

Not only is it not illegal, it works just as well.   Consider my slightly
changed version of your program:

Foo = 1
function Bar()
    local Foo = 5
    do
        local Foo = 7
        print( Foo )
    end
    print( Foo )
end
Bar()
print( Foo )

[1017]~: /usr/bin/lua -f luatest
7
5
1

...three foos in Lua 4 as well.  Which means I *really* have to go back and
read the manual again...
