This is actually what I've been thinking during this discussion. I'm not really seeing a pressing need for strict in one-liners, but phiosophically, I can understand why one might want to have strict on in all cases. So, if we think this is something that actually needs solving, this mechanism seems reasonable to me. This discussion got me looking at http://design.perl6.org/S19.html which may need an update, it says perl6 has no -M but Rakudo supports it; which is correct? The 5to6.pod document in the doc directory says it does exist. I lean towards feeling the docs should be more correct/reliable than the design documents, as that's where people outside the p6 creation bubble will be looking for info (not that, at the moment, they necessarily *are* more correct/reliable - work in progress and all...). All that said, there doesn't, at a quck glance, seem to be any equivalent to Perl 5's perlrun document, which would detail the command line flags.

slurpy hash
Given the code:
use v6;
sub speakhash (*%hash) {
say %hash{};
}
speakhash(1, 2, 3, 4, 5, 6);
I get the error:
Too many positional parameters passed; got 6 but expected 0
in 'speakhash' at line 3:slurphash.p6
in main program body at line 7:slurphash.p6
According to the UsingPerl6 draft document, *%hash slurps all the
remaining unbound named arguments into a hash.
So, it looks to me as though the arguments given to the speakhash()
subroutine should be slurped into %hash. Regardless, it strikes me as
odd that Rakudo* seems to think that the subroutine should expect *0*
arguments.
So... clearly there's a problem here, but I'm not sure if it's with
Rakudo* or with my thinking. :-)
Any thoughts on this matter would be appreciated.
many thanks,

The key here is named arguments; You've invoked the speakhash sub

Try this:
