Well - it's a miracle... I just tried the code you posted, and indeed PHP
(v.4.2.2) allows numeric identifiers - BUT ONLY as long as you're accessing
it indirectly.
Example:
$key = 0;
$$key = 'some data'; // works
echo $$key; // works
echo "Key 0: $0" // prints "$0", not the content (wrong)
echo $0; // error "unexpected T_DNUMBER"
