Are PHP label names reserved globally?

I know goto won't work between functions and classes, but are the label names reserved? Can I successfully use the same label name in separate closures?


$x = function()
    goto end;
    echo "From X\n";

$y = function()
    goto end;
    echo "From Y\n";


From X
From Y
