Hi,

$ perl6 --version
This is perl6 version 2013.11 built on parrot 5.9.0 revision 0

I've noticed that in some cases it is possible to cause an endless loop
with hyper operators and an empty parcel (if the empty parcel is allowed to
be extended) e.g.​:

True »+» ()
() «-» ("a",)

and so on ...

Thanks! This was fixed in Rakudo commit 0bc3a0455 ( rakudo/rakudo@0bc3a0455 ) and tests were added in Roast commit 966d85bc95 ( Raku/roast@966d85bc95 )

Closing this ticket as resolved :)
