Re: [perl #57170] In rakudo, defining a class deriving a not yet defined class produces a Null PMC access

[Carl Mäsak]

It turns out that 'class A is B {}; class B {}' is not a valid Perl 6 program.

<TimToady> @messages
<lambdabot> masak asked 7h 17m 55s ago: is `class A is B {}; class B
{}` allowed in Perl 6?
<TimToady> @tell masak "is B" is not allowed unless B is already known
to be a trait or type; only subroutines can be post-declared

Still, it should preferably generate some other error than a 'Null PMC
access' parsefail... so the bug still stands.
