Perl stores both the numeric and string representations of a scalar
variable.  The active representation is whichever was used last.  Most
operators and functions in Perl don't care which representation is active.
As documented, however, the bitwise operators (& | ^ ~) behave differently
depending on whether the operand(s) are numbers or strings.
