Thank you very much for your patch.

I'm a bit confused though - why is prefix​:<=> in IO.pir, while .get is
in Iterator.pir - both seem to have the same function. Is there a good
reason for that?

Cheers,
Moritz

Iterator will support .get. It's unclear whether IO will as well,
or whether it will stay exclusively with .getc/.readline. They were
both supposed to support prefix​:<=> but prefix​:<=> was not implemented
for Iterator in rakudo.

Even if both support .get, Iterators and IO objects will have different
implementations. This is the implementation for Iterator, which is
currently mostly a boxed Parrot primitive type.

As I did not know what the eventual intent was with IO, I did not try
to implement .get also for the IO class.

It's fairly certain that IO will use .get -- indeed, it
was IO that caused us to change from prefix​:<=> to .get in
the first place.

Even if both support .get, Iterators and IO objects will have different
implementations. This is the implementation for Iterator, which is
currently mostly a boxed Parrot primitive type.

Iterator probably ought to become a role instead of a class.
In that sense we will likely stop using the Parrot primitive
type for our Iterators (or they'll be suitably wrapped in
something that does the Iterator role).

Patch will not be relevant now since Iterator has been totally
re-implemented since; closing ticket.
