  I would bitwise combine 2 and 8 and get ":". Yes, I was confused too.

  You must have used two strings. Bitwise combination of two strings is different in Perl, than of integers. In fact, if any operand is a number, Perl will try to convert the other argument to a number, too.

  print "2" | "8";

  Result:

  :

  vs.

  print 0+"2" | "8";

  Result:

  10

  In the case of strings, Perl will bytewise combine the bits of the bytes of which the strings consist. For numbers, Perl just combines the integers, commonly 32 bits each.

    I couldn't find this documented anywhere. Is it?

      There's the entry on "Bitwise String Operators" in perlop [perldoc.com].
