start of Mathx::Stat

Hello, I've uploaded Mathx::Stat to cpan's holyghost Perl6 directory. It contains a statistics package. I needed the above for a Markov strategy package for writing prospection in Perl 6 games, e.g. with SDL2::Raw for graphics. This starts from Markov startegies unto Statistical Chaos theory

Re: Malformed UTF-8 ???

It's redundant for this code. `$foo` means data that's to be treated as either a single item or as a single item container containing a single item. `$$foo` means put the single item in $foo into a single item container containing it. Given that this appears on the right of `=` the single item i

Re: What is |c ?

|foo in a signature captures all remaining arguments using a local variable called foo. sub foo (|foo) { foo } say foo 42; # \(42) -- raiph On Sun, Oct 14, 2018 at 10:21 AM ToddAndMargo via perl6-users < perl6-us...@perl.org> wrote: > Hi All, > > Over on > > https://docs.perl6.org/routine/s

Re: Malformed UTF-8 ???

I see no significant difference beyond the inside of your proc and the outside of the code you've shown. The extra `$` in `$$proc` is redundant. (I don't understand why you have it.) The `(...)` is the same as my `: ...`. It can wait until you switch to `slurp`. I wouldn't expect it to make an

Re: Malformed UTF-8 ???

Almost certainly your problem is elsewhere. When you refer to a variable as a *value* then you get its *value*. So: return $ReturnStr returns $ReturnStr's *value*, not the variable. Your code returns such a value, which will be an immutable string. So I think the error message you're getting

Re: Malformed UTF-8 ???

Are you sure the error message you showed applies to the line you showed? This code works fine: spurt 'foo', 'bar'; my Str $ReturnStr = ""; $ReturnStr = 'foo'.IO.open.slurp-rest: enc => 'utf8-c8'; say $ReturnStr; # bar -- raiph On Sun, Oct 14, 2018 at 10:52 AM ToddAndMargo via perl6-users < per

Re: Malformed UTF-8 ???

I just tried slurp-rest with a specified encoding and it worked fine. Are you sure you don't bind $ReturnStr between the declaration you've shiown and the use you've shown? -- raiph On Sun, Oct 14, 2018 at 10:35 AM ToddAndMargo via perl6-users < perl6-us...@perl.org> wrote: > On 10/14/18 2:29 A
