The aim of the implementation is to provide the PerlIO API in a flexible
and platform neutral manner. It is also a trial of an "Object Oriented
-C, with vtables" approach which may be applied to perl6.

in the table correspond to C<stdin>,C<stdout> and C<stderr>. The table
in turn points to the current "top" layer for the handle - in this case
an instance of the generic buffering layer "perlio". That layer in turn

The above is roughly equivalent to a "stdio" buffered stream, but with
much more flexibility:
