I perceive there are two basic approaches that can be taken.

One of them provides hooks in and/or out to user-level code to handle the
various events surrounding standard <> processing, but the readline and
print operations would remain unchanged (presumably for speed purposes).
This seems to be what you're talking about.

The other of them would be less hacky but perhaps not efficient enough for
some purposes.  Perl code can open ARGV and ARGVOUT and/or assign tied
filehandles to them.  Then all the <> processing, period, happens via
"normal" (ahem) tied filehandle magic.  This is something that could be done
today, modulo the '<> in list context' problem mentioned in overload.pm.

Is this a good summary?

Hard to know which of them is worth doing.
