Re: EVAL?

Exactly what it says: eval is a code injection attack waiting to happen. If you actually need it, you get to do your own data sanitization, and you tell Perl 6 you did so with "use MONKEY-SEE-NO-EVAL;". On Wed, Jun 13, 2018 at 3:22 PM ToddAndMargo wrote: > Hi All, > > I am converting a program

Re: RFE: eval documentation

I think the message is obscure for a reason: the last thing you want is for someone to make an insecure module look "safe" by just dropping that pragma into it. You want to make them think about what they are doing. On Thu, Jun 14, 2018 at 1:32 PM ToddAndMargo wrote: > Dear Perl6 Developers, >

Re: EVAL?

That's actually the origin of it: pragmatic / real-world behavior, as opposed to idealized situations. On Thu, Jun 14, 2018 at 1:47 PM ToddAndMargo wrote: > On 06/14/2018 10:43 AM, The Sidhekin wrote: > > > >More relevant, Perl 6 documentation: > > https://docs.perl6.org/language/pragmas >

Re: EVAL?

in this sense, since at least the 1960s and probably earlier. So also check various CS glossaries. Such as FOLDOC: http://foldoc.org/pragma On Thu, Jun 14, 2018 at 1:52 PM ToddAndMargo wrote: > On 06/14/2018 10:49 AM, Brandon Allbery wrote: > > That's actually the origin of it: pr

Something's wrong with the data file you are reading. Perl 6 is expecting UTF-8 encoding and getting something else (usually an ISO-8859 encoding). On Sat, Jun 16, 2018 at 1:09 AM ToddAndMargo wrote: > rakudo-pkg-Fedora28-2018.05-01.x86_64.rpm > $ perl6 -v > This is Rakudo version 2018.05 built

Re: need sort help

Brent thinkoed that slightly. (Forgot that first use of a placeholder "declares" it, and thereafter you don't use the ^. Which then collides with the local "my" variables.) > @x.sort: { >my $a = $^x ~~ m:g/\d+/; >my $b = $^y ~~ m:g/\d+/; >$a[6].defined cmp $b[6].defined >?? >
