Net::OpenSSH relies on Scalar::Util's dualvar function (which is only available in the XS version of Scalar::Util) to create a single scalar holding both an integer and string value. When the scalar is used in a numeric context, the integer value comes out, and when the scalar is used in a string context, the string value comes out. I'm trying to write a quick and dirty PP version of dualvar so I can move on with my life.</div><div apple-content-edited="true"><br></div><div apple-content-edited="true">I seem to remember seeing this being done, but no amount of googling is getting me there.
