Good point, but when using 
'/(?:^|\\s+)(and|x?or|&&|\\|\\||[!()])(?:\\s+|$)/i'
to parse 'auth edit && ( auth edit || false )', I got (before the loop):

$terms: Array
(
    [0] => auth edit
    [1] => &&
    [2] => ( auth edit
    [3] => ||
    [4] => false
    [5] => )
)

evaluting to (after the loop):

$terms: Array
(
    [0] => 1
    [1] => &&
    [2] => ( auth edit
    [3] => ||
    [4] => 0
    [5] => )
)

which is a bit annoying...

Cheers,
Dom
