(This is why shells produce 255 for command not found.) And... well, try these in perl 5 and see what you get.

Hi,
I've tracked this issue to this commit:
https://github.com/rakudo/rakudo/commit/6b935928a52be5819b6d384b1596e0125250a18b
If you try running this piece of code in REPL, it'll exit the REPL after
printing the error:
[1..99].map:{[$_%%5&&'fizz', $_%%3&&'buzz'].grep:Str}
Here's the error:
zoffix@VirtualBox:~/CPANPRC/rakudo$ ./perl6-m
To exit type 'exit' or '^D'
You may want to `panda install Readline` or `panda install Linenoise` or use
rlwrap for a line editor
> [1..99].map:{[$_%%5&&'fizz', $_%%3&&'buzz'].grep:Str}
===SORRY!===
Cannot resolve caller grep(Array: ); none of these signatures match:
($: Bool:D $t, *%_)
($: Mu $t, *%_)
zoffix@VirtualBox:~/CPANPRC/rakudo$
The issue doesn't happen with every exception and I wasn't able to golf the
above code.
