So we can start the battle of style: would you rather have a clumsy, useless loop (or map), or rather two clumsy, lines, one with declaration, one with initialization?
Perl 6 to the help, if you don't mind wrapping your head around function style a bit, you can use the zip operator Z:
pugs> my @good = <a b c>
("a", "b", "c")
pugs> @good Z 1 xx @good
(("a", 1), ("b", 1), ("c", 1))
Pugs doesn't flatten the list correctly, so you can't assign it to a hash in pugs, but a correct implementation will allow that. (Notice also the beauty of not needing any grouping parenthesis, because the precedence levels are just right(tm)).
# Perl 6:
my %hash = @good Z 1 xx @good
