there're optional ways to use the permission:

along with

$permissions['myhackpermissions'] & $vbulletin->bf_ugp['myhackpermissions']['canfoo']

you can use

$permissions['myhackpermissions'] & $vbulletin->bf_ugp_myhackpermissions['canfoo']

or

$permissions['myhackpermissions'] & 1

the last one is the shortest one but then you won't understand what it does, 1 is the value of <bitfield> tag, just similar as the old permission settings.

I found that the 'canfoo' is case sensitive, this took me almost a day to figure out lol
