<masak> rakudo: my $r = 1..9; $r.pop; say $r.perl # pmichaud: if
ranges are immutable, how come I can pop from them?
<p6eval> rakudo 2dded8: OUTPUT«1..8»
<pmichaud> masak: there was a spec change at npw that declares ranges
as immutable. Rakudo hasn't caught up.
<pmichaud> masak: in particular, .pop and .shift are now gone from
that part of the spec.
<pmichaud> masak: indeed, part of the reason that rakudo hasn't caught
up is because Ranges need to be refactored to be properly Positional,
and doing that means we really need a good understanding of captures.
Hence, thediscussion today.

<pmichaud> we also need to remove the tests for .pop and .shift from the suite.
<masak> I like ranges better when they're immutable.
<pmichaud> yes, me also.
