NAME

       IO::Handle::Iterator - Iterator based read handle

SYNOPSIS

           IO::Handle::Iterator->new(sub {
               return $next_line; # or undef on eof
           });

DESCRIPTION

       This class lets you define a read handle with a few fallback methods (like "read") using a
       single callback that behaves like "getline".

       This is similar but much simpler than:

           IO::Handle::Prototype::Fallback->new(
               __read => sub { ... },
           );

       The reason being that the IO::Handle::Prototype::Fallback implementation will try its very
       best to behave correctly (i.e. respect the value of $/), whereas this implementation
       assumes it's fine to return things that aren't exactly lines from "getline", so the values
       are just passed through.

READ BUFFERING

       When a method that requires buffering is invoked the handle is reblessed to a subclass
       which handles buffering.

       Calling "getline" again on this object will return the value of the buffer and return to
       the normal iterator class.
