[Python-ideas] Iterating non-newline-separated files should be easier

[Guido van Rossum]

I don't have time for this thread.

I never meant to suggest anything that would require pushing back data into
the buffer (you must have misread me).

I don't like changing the meaning of the newline argument to open (and it
doesn't solve enough use cases any way).

I personally think it's preposterous to use \0 as a separator for text
files (nothing screams binary data like a null byte :-).

I don't think it's a big deal if a method named readline() returns a record
that doesn't end in a \n character.

I value the equivalence of __next__() and readline().

I still think you should solve this using a wrapper class (that does its
own buffering if necessary, and implements the rest of the stream protocol
for the benefit of other consumers of some of the data).

Once a suitable wrapper class has been implemented as a 3rd party module
and is in common use you may petition to have it added to the standard
library, as a separate module/class/function.
