\& open my $fh, ">", \e$scalar or die;

A filehandle is opened but the file operations are performed \*(L"in\-memory\*(R"
on a scalar variable. All the normal file operations can be performed
on the handle. The scalar is considered a stream of bytes. Currently
fileno($fh) returns \f(CW\*(C`undef\*(C'\fR.
.SH "IMPLEMENTATION NOTE"
.IX Header "IMPLEMENTATION NOTE"
\&\f(CW\*(C`PerlIO::scalar\*(C'\fR only exists to use XSLoader to load C code that
provides support for treating a scalar as an \*(L"in memory\*(R" file.
One does not need to explicitly \f(CW\*(C`use PerlIO::scalar\*(C'\fR.
