Yeah, looks good on rakudo-j, too:
$ ./perl6-j -e 'class A { has str $.x; method BUILD(:$!x) { } }; say
A.new(:x).x'
foo
I'm marking the isse as TESTNEEDED.

Current behavior (don't have a rakudo-j here):
$ perl6-m -e 'class A { has str $.x; method BUILD(:$!x) { } }; say
A.new(:x).x'
foo
If r-j now works too, we can move to TESTNEEDED.

Re: bash and pm6 question
With perl5, that could have been something like. "perl -Mmy -e ...", but I don't have access to a perl6 at this instant to compare. There should be a flag you can use to include a module into the.running environment before evaluating the "-e" code. Using "use" within the "-e" string should work, too.

"is copy" instead creates a new mutable container holding a copy of the thing being bound, so that changes to it are possible but won't affect the original. -- brandon s allbery kf8nh sine nomine associates allber...@gmail.com ballb...@sinenomine.net unix, openafs, kerberos, infrastructure, xmonadhttp://sinenomine.net

Re: help with map and regexp
You can also use a whatever star with the subst method to avoid the block
entirely, and just chain method calls:
my @fields = $line.split( ',' ).map: *.subst(/\'/, "", :g).subst(/^\"|\"$/,
"", :g);
