IO::String is a module that will most likely do what you want, but it includes
Note that perl-5.8 and better has built-in support for "in
memory" files, which are set up by passing a reference
instead of a filename to the open() call. The reason for
using this module is that it makes the code backwards
compatible with older versions of Perl.
I tried it in perl 5.9.2 and get:
$ perl -we 'open F,">",\$f; select F; print "hello"; print ", world"; print STDOUT "<$f>\n"'
for more info
perldoc -f IO::String;
