Perl 6 does not defend itself against invalid options. Using an invalid
option results in an ungraceful death rather than a valid error message.

E.g.
$ ./perl6 -x "say 'Hi';"
Error​: file cannot be read​: -x
current instr.​: 'parrot;PCT​::HLLCompiler;panic' pc 158
(src/PCT/HLLCompiler.pir​:103)

Earlier this year there was some discussion of defining a set
of standard command-line options that would be common to all
Perl 6 implementations, and so we've been holding off on
argument processing until that's resolved a bit more. I haven't
heard much more about it since January -- perhaps we should poke
perl6-language for ideas...?

Thanks!

Should it matter what's in the "allowed" class? From the beginning, there
ought to be a default "if I don't know what this is, spit it back" action.
What happens before that point is irrelevant.

Rakudo r31409 assumes that all flags that it hasn't heard about are
program files.

$ ./perl6 --help
./perl6
Usage​: perl6 [switches] [--] [programfile] [arguments]
[...]
$ ./perl6 --kelp # a kind of seaweed
Error​: file cannot be read​: --kelp
[...]
$ touch -- --kelp
$ ./perl6 --kelp # quietly succeeds

This is likely to be fixed as part of S19 development, so I'm
marking this ticket as stalled until then.

Now dies with "no such option -x"
