IO::String
=head1 SYNOPSIS
=begin code
    use IO::String;

    my $buffer = IO::String.new;
    {

DESCRIPTION

Sometimes you want to use code that deals with files (or other
file-like objects), but you don't want to mess around with creating
temporary files.  This includes uses like APIs that for some reason
don't accept strings as well as files as targets, mocking I/O,
or capturing output written to the terminal.  That's why this module
exists.  Loosely based on Perl 5's IO::String.
