Re^2: XML::Writer oddness

Thanks. That makes sense. Courtesy of XML::Writer, \$doc is a reference to an XML::Writer::_String object instead of a reference to a scalar, as I expected.

gzip does lots of different things depending on its first arg. Of course, the docs for Gzip say that if the first arg isn't something it expects (a filename, filehandle, scalar reference, array reference, or an Input FileGlob string), it will return undef. Instead, it dies. How rude.

\$doc is a reference to an XML::Writer::_String object instead of a reference to a scalar, Well, it's both, seeing as `$doc` is a scalar. And furthermore, the contents of the scalar are obviously meant to be used as a string (If not, `$doc` would be given a reference.) So don't be afraid to use it as a string.	[reply] [d/l] [select]

Magics collided. Happens. Using `"$doc"` instead of `$doc` you make a copy.	[reply] [d/l] [select]
