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.
