Yes, probably just defining read() and readline(

Thanks for the answers everyone.
Denis, I wish to wrap an already open file handle basically, so simply
extending and overriding doesn't help - my proxy won't be instantiated
like a file, just used like one and if not intercepting I need to
delegate down to the proxied "real" handle. If I'm missin

Neat stuff - but not applicable for me I think:
1. I receive the handle. I need this function in a CGI script for
example, so

Hello,
I'm trying to intercept one or more methods in file-like objects (in
this particular case just sys.stdin really), essentially I need a
