You're going to have to try harder if you want Haskell to outgolf Perl 6 here. The following all work in Pugs and are shorter than your Haskell version.
sub reverseWords ($_) {~reverse .comb} sub reverseWords {~reverse comb @_} my&reverseWords:={~.comb.reverse}
The first two could even be construed as readable.

    If we're really concerned about golfing to the fewest strokes, you should check out the UCBLogo solution in my post down a few in the discussion. In UCBLogo, the number of (key)strokes needed is zero.

    print substr("Just another Perl hacker", 0, -2);

[Corion]: On the upside, I spend a lot of time thinking this weekend about how to actually implement rate limiting for futures, and if things work out, maybe even loading a configuration from an external file makes sense
[Corion]: I've also found some interesting invariants that I have to think/write about more. A simple rate limiter will never change the order of the input, while a limiter that allows for parallel execution will change the order. But my API currently allows for bo
[Corion]: ... for both, and I'm not sure if I want to add the cruft from the parallel API (a token that you need to hold on to while you hold the lock) to the rate limiting API too, to allow seamless up/downgrades, or not.
[Corion]: Also, rate limiting will look great with await: my $token = await $limiter-> limit($hostname); instead of my $f = $limiter->limit( $hostname )->then(sub { my( $token)=@_; ... });
