Perl does have a feature of being able to open a file handle/stream on a string buffer rather than external media. There are several reasons why it is sometimes useful to treat a string as if it were a file. Three reasons that come to mind:

For more information on this feature of Perl, see open and search for the phrase "Perl scalars". I believe support has been part of the Perl core since 5.8 (which is why I presume Disciplus tested that version - which is really old). See also IO::Scalar and IO::String. IO::Scalar can be used to bring support for in memory/scalar backed file handles to even earlier versions of Perl.
