Typo alert - you were printing $x/@x, not y
perl -e 'my @y=("ab",12,"xx");print "y=@y\n"'
y=ab 12 xx
perl6 -e 'my $y=("ab",12,"xx");print "y=$y\n"'
y=ab 12 xx
in p5, that's the $" (use English; $LIST_SEPARATOR) var that is used to
separate lists when interpolated in a string:
perl -e 'my @y=("ab",12,"xx"); $" = "|"; print "y=@y\n"'
y=ab|12|xx
perl -e 'use English; my @y=("ab",12,"xx"); $LIST_SEPARATOR = ", "; print
"y=@y\n"'
y=ab, 12, xx
P6 complains
Unsupported use of $" variable; in Perl 6 please use .join() method
so:
perl6 -e 'my $y=("ab",12,"xx"); print "y=", $y.join(", "), "\n"'
perl6 -e 'my @y=("ab",12,"xx");print "y=", @y.join(", "), "\n"'
