From @masak

Calling .perl on a self-referent structure makes Rakudo r31152 hang.

$ ./perl6 -e 'my @​a = (1); @​a[0] := @​a; @​a.perl'

<masak> pmichaud​: what about @​a[0] := @​a ?
<pmichaud> masak​: I don't know about that one. :-)
[...]
<masak> :)
[...]
<pmichaud> part of me thinks that ends up with a self-referential structure
<masak> I hope so
<masak> that seems to be what's happening in at least one case in
Rakudo right now
<masak> question is, should .perl be able to handle that, and if so, how?
<moritz_> masak​: it should
<moritz_> perhaps it should emit something like 'do { my @​x = (...);
@​x[0] := @​x; @​x }'
* masak submits rakudobug

I'm going to mark this ticket as stalled until we have a good idea of
how self-referent structures should be handled in the output, either
through the spec itself or the spectests.

Thanks!
