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 )

7
5
1

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