in reply to Replaying Santa Claus Golf Apocalypse with Pugs/Perl6

This is the best I could come up with for tail.p6: 
my@l=(open@ARGS[0]).readline();
my$i;$i=@l-10 if@l>10;
say@l[$i..Inf];

It seems to pass all tests for current Pugs svn build.

Update: After discovering that the good old ternary operator was renamed to ?? ::, I came up with the slightly more elegant solution: 

my@l=(open@ARGS[0]).readline();
my$i=@l>10??@l-10::0;
say@l[$i..Inf];

This is exactly one character shorter...:-)

Update2: I have just discovered the = $filehandle operator in list context, so, take this one: 

my@l= =open@ARGS[0];
my$i=@l>10??@l-10::0;
say@l[$i..Inf];

In fact, my@l==open@ARGS[0]; seems to work too, but, in my opinion, this should better be a bug...

    I don't know if it's implemented yet, but you should be able to make that last line: 
        say@l[$i...];

    Combining with the previous line gets you 
        say@l[(@l>9??@l-10::0)...];

    I took the liberty of changing your 10 to a 9. The final semicolon should not be required eventually either.

      Again, Pugs knows better...:-) It does not seem to work with the current svn build. 

      say@l[(@l>9??@l-10::0)...];

      Yes, I tried similar solution myself, too, but Pugs does not let me to incorporate the ternary operator into the array index. What is pretty interesting playing around with Pugs is that usually it proves itself much more flexible in parsing complex Perl 6 statements than I would have expected it, but every now and then even the simplest ideas fail with some obscure error messages. It is getting better all the time, though.

        The trailing ... was borked by the overeager "spre" conversion. It now works again in the trunk.

        The ?? :: parsing, now works inside brackets, too, so all two forms above should totally work. Yay for golf-driven development!
