I'm not sure how much more common static scoping is in this context.  Given
the following script:

foo()
{
        local bar

        bar=inside
        foo2
}

foo2()
{
        echo $bar
}

bar=outside
foo
echo $bar

bash, mksh, zsh, dash, and the FreeBSD 8 sh all print `inside', then
`outside'.  ksh93 (after making the appropriate modifications to the
script syntax), is the only one that prints `outside' and `outside'.
