Converting a string to a filehandle

Dear expert,

Is there a way to do it? Module for it? Suppose I have this large string.

my $string = 'foo bar
qux woo
etc etc';

I would like to convert that string as if it is stored inside a file, and bypassing the file creation step.
For example,

my $filehandle = do_sth_to_convert($string);

Such that I can straight away do things like:

while (<$file_handle> ) {
print;
}

I think you want the IO::Scalar module.

Yes, since 5.8.0 that's built-in:

open my $filehandle, '<', \$string;
