Roaming the dusty halls of some legacy system tools, I found some code that takes IO-Stringy as a dependency.  Only to use it for IO::Scalar... only to support sending to non-filehandles... which is an unused feature of the system.  There are no callers of the carefully-built "change output stream" method.

As the icing on the cake, Perl has had native support for doing this since 5.8, by passing a scalar reference instead of a file name: open($fh, '>>', \$string_out);

This legacy code has only ever run on Perl 5.10.0 and newer.  The dependency has always been unnecessary, unused, and overbuilt.
