Perl references are indeed similar to C pointers, in that a reference
variable contains the "location" of another variable and allows one to
indirectly access the value of that variable, but there are some
differences. For example, one cannot do arithmetic on Perl references, e.g.
incrementing a reference to iterate through an array.
