Think of every position as a wheel in a mechanical counter.

There are three kinds of wheels 0-9, a-z and A-Z which can be independently be chosen for each position.

Clearer now? =)

the increment is done as a string, preserving each character within its range, with carry: print ++($foo = '99'); # prints '100' print ++($foo = 'a0'); # prints 'a1' print ++($foo = 'Az'); # prints 'Ba' print ++($foo = 'zz'); # prints 'aaa'

    [LanX]: unusual that "Pimp my Bride" never made it into TV (?)
    LanX sighs ... no idea stupid enough
    [choroba]: "Smack My Bitch Up" did, though
    [Eily]: that's the internet for you LanX
    [Eily]: and I'm pretty sure there's a rule somewhere that states that the stupider the idea, the more likely it is to already have been done
