Why add prototypes? In C, function prototypes enable compile-time type
checking of function arguments, and are generally a good thing. Perl
prototypes aren't designed to do that. Instead, the "$" prototype adds
an implicit typecast in front of function arguments, converting arrays
and hashes into scalar arguments. For example, the "$" prototype
converts an array of letters ("a",b","c","d") into a count of the
number of elements (e.g. "4"). Is this really what you want to do?

See the following mail for more information on how prototypes work:
