Why does Perl not have overloaded functions?

Because you can inspect the argument count,
return context, and object types all by yourself.
In Perl, the number of arguments is trivially available
to a function via the scalar sense of @_, the return
context via wantarray(), and the types of the
arguments via ref() if they're references and
simple pattern matching like /^\d+$/ otherwise.
In languages like C++ where you can't do this, you
simply must resort to overloading of functions.
