    Just did the Perl 6 example on my Macbook Air and got a very different time! I have a feeling the poster is using the JVM build without understanding that it has about ~8 seconds start up time regardless of what you do, even something like `perl6 -e ''`

    $ perl6 --version
    This is perl6 version 2013.09 built on parrot 5.5.0 revision 0

    $ sysctl -a | grep machdep.cpu.brand.string
    machdep.cpu.brand_string: Intel(R) Core(TM) i5-2557M CPU @ 1.70GHz

    $ time perl6 stuff.p6
    My multiples are: 3 5 6 9 10 12 15 18 20 21 24 25 27 30 33 35 36 ... *snip* ... 993 995 …

    My times for the Perl 5 version for comparison:

    real 0m0.064s
    user 0m0.010s
    sys 0m0.015s

    So my Mac has a slower time for the Perl 5 code so I'd imagine the OP would have a slightly better time than 1s for the Perl 6 code running in the latest R* parrot build?

    Do note that you can use @*ARGS instead of providing a sub MAIN; though the latter will give you a usage message when you don't supply the max and if you write

    sub MAIN( Int $max = 1000 )
    instead, you'll even get a helpful error message if the user writes "over nine thousand" instead of a number.

    Also, for interpolating arrays into strings, you can also just write

    "My multiples are: @multiples[]".say;

    And another thing: I think "1 ..^ $max" looks prettier than "1 .. $max-1".

    In your P6 code you have this line of code:

    unless any(@multiples) $start {

    That looks like TTIAR (two terms in a row) to me (syntax error).

    The code is still mangled :(
