Is this a bug?

This code: 1 #! /home/guru/bin/perl6 2 3 # Ask for some lines and output them in reverse 4 # Work out the appropriate EOF symbol for the OS 5 6 my $EOF = "CTRL-" ~ ($*DISTRO.is-win ?? "Z" !! "D"); 7 8 say "Please enter some lines and end them with $EOF"; 9 10 say { for reverse lines() {} }; 11 12

Re: Is this a bug?

I think you want: .say for reverse lines; not sure what you are trying to achieve otherwise, but: say { } producing something like -> ;; $_? is raw { #`(Block|170303864) … } feels entirely correct to me. :-) Liz > On 18 Sep 2016, at 21:52, Parrot Raiser <1parr...@gmail.com>

Re: Is this a bug?

Remember you can call a block with parentheses: > say { 11 + 31 }; -> ;; $_? is raw { #`(Block|140268472711224) ... } > say { 11 + 31 }(); 42 On Sun, Sep 18, 2016 at 12:58 PM, Elizabeth Mattijsen wrote: > I think you want: > > .say for reverse lines; > > not sure what you

It is the .perl representation of a Block. > On 18 Sep 2016, at 22:49, Parrot Raiser <1parr...@gmail.com> wrote: > > say { $_ } was the correct thing to use there. (I'm trying to avoid > any mention of O-O for the moment.) > say {} was a "what happens if I do this" exercise. > > What is this

Re: This seems to be wrong

D’oh! I’m blind. But I see there’s a multi method Str defined on Any, and you can’t do @inputs.map( .Str ), either (Use of uninitialized value $_ of type Any in string context). Why not? (There’s no multi method Num on Any, even though the docs about Cool seem
