Re: How the auto-increment operator works?

Think of it as counting in a weird base-26: 99++ —> 100, Ay++ —> Az, Az++ —> Ba, so zz++ —> aaa.

When you are counting in base-10 and you reach 99, you add a leading "1" instead of wrapping back to only "00". The magic autoincrement does the same with letters: when you reach the end of the alphabet, it adds a leading "a" while wrapping back instead of repeating a previous value. This is also why "z" becomes "aa": $ perl -e '$X = "z"; print $X, "\n"; $X++; print $X, "\n";' z aa	[reply]
