Re: A problem with native CArrays

The [+] works because of an optimization. If you use the core :<+> it instead calls the .sum() method. Since CArray has a sum method, that gets called instead. On Sun, Sep 30, 2018 at 4:28 AM Fernando Santagata wrote: > > Hi, > > I was hunting for a bug in my code, this one: > > my @a :=

Todd, allow me to distill the situation from my POV. There are many sources of Perl 5 docs. "perldoc -f ..." is one of them, and it works well for you. There are also a choice of Perl 6 docs. "https://docs.perl6.org/; is one of them, and it doesn't work well for you, but of all the perl6 docs,

Hi Todd, I disagree with you. The P6 documentation can certainly be improved, but it is quite good and clear already. Remember that it is technical documentation, not a tutorial. And the example you chose to give does not support your point: the P6 documentation for join is just at least as clear

Re: Could this be any more obscure?

the words method is extracting items from an input string. The $limit parameter tells the words method to extract not more than $limit items from the string. Setting the default to Inf only tells the method to extract as many items as it can from the input (i.e. to process the whole string),
