well as discussed before this code is an relict from register_globals=on

why not? you can even use ä,ü,ö without using ${' äöü '}, should these 
be legal - let the user decide how to write his code

I'm not sure if I already said, using variables varialbles this might be 
helpful

$a=array('foobar 1','foobar 2','foobar 3','foobar1',' foobar 1');
foreach($a AS $val)   {
    $$val=somestuff(); }

this is fairly legal right now and of course this should be legal to be 
able to access them manually

echo ${'foobar 1'};


if wisely used an interesting feature
