You mean "open F, '<:encoding(Guess)'" ? The answer is no because in
order to guess encoding you have to actually read it. And to allow
file access after the guess you have to rewind the filehandle,
something you can't always do (consider socket).
So long as you can detect the encoding in the 1st buffers-worth
(where your layer gets to decide on buffer size) then with -Duseperlio
you can rewind a socket. One of the motivations for PerlIO's "unread"
semantics was for exactly this case.
Now it may not make sense to put logic for that into :encoding itself
so perhaps we need :guessencoding or :via(GuessEncoding) ...
