Hi
We want to use Perl 6 as Kafka client. When I want to save the offset in
the queue after I processed the message I get some MoarVM panics:
MoarVM panic: Internal error: zeroed target thread ID in work pass
or sometimes
MoarVM panic: Internal error: invalid thread ID 8614688 in GC
Sorry, I forgot about
# perl6 -v
This is Rakudo version 2019.03.1 built on MoarVM version 2019.03
implementing Perl 6.d.

Betreff: MoarVM panic when using PKafka
Hi
Dear Raku programmers
I have a hash with arrays as value. Out of that I wanted to get a flat list
with all the entries in the value arrays. My first intuitive attempt was to use
flat, but somehow that only works with an additional map step:
$ raku
To exit type 'exit' or '^D'
> my %hash-with-ar
Dear Raku experts
I have a little patch which adds another library include path and installation
site named "foo" which points to "/opt/foo/lib", see attached patch.
That worked (in a similar fashion) well with 2020.02, but with 2020.05 it fails
on the following test:
$ cat foo.rakumod

Hi
I miss an error on my first invocation of `c` below:

It's near the top of the `Nil` doc page you linked:
Any method call on `Nil` of a method that doe
ne of them is
returning Nil, then perhaps we have a bug. Could you elaborate on the
situation where you encountered this?

Hi Ralph
I understand that this is about avoiding the pyramid of doom.
And it is enjoyable that it can be avoided. Opt in.
No programming language I worked so far has this semantics of method
call. So we might name it differently as it is doing something
different... -> that is the trap.

see that some data or state is incorrect. And the
problem with incorrect data is that you might not even spot it.
