<masak> jonathan​: how come `./perl6 -e '$_'` gives the error "too few
arguments passed (0) - 1 params expected"?
[...]
<jonathan> masak​: Please submit a ticket about that.
<masak> jonathan​: oki

<pmichaud> I think it's that $_ is causing the outer sub to have a parameter
<masak> how sinister
<pmichaud> yes, it's a rakudo bug

From @masak

The attached patch fixes the bug #​55184​: "The presence of $_ in
programs produces an error", reported a while back.

<http://rt.perl.org/rt3//Public/Bug/Display.html?id=55184>

It's a limited fix, and I'd be happy to hear how it could be improved.
All rakudo tests pass after the patch has been applied.

Cheers,
// Carl

Thanks for the patch; I'm rejecting it (or at least placing it on hold)
for now because I don't like promoting the __FLAG_VARIABLE meme that is
rapidly spreading itself throughout the code. (It reminds me of the way
that references to 'infix​:,' ended up proliferating throughout actions.pm.)

All of the $_, $!, and $/ handling in Rakudo needs to be refactored; at
this point I'd rather place things on hold for that refactor than add
even more code to the burden. (I'm expecting to get to the refactor in
the next 4-5 days.)

Thanks again!

Understandable. If nothing else, the making of this patch has given me
some insights into rakudo guts, which must be a good thing.

this point I'd rather place things on hold for that refactor than add

Looking forward to that refactoring. Keep up the good work!
