<amoc> rakudo: my @a = <one two>; @a[-1] = 'zero'; @a.perl <p6eval> rakudo f8b6ae: RESULT«"[\"one\", \"two\"]"» <amoc> it is a bug, right? <masak> amoc: [*-1] <amoc> rakudo: my @a = <one two>; @a[*-1] = 'zero'; @a.perl <p6eval> rakudo f8b6ae: RESULT«"[\"one\", \"zero\"]"» <masak> S09. <jnthn> I think -1 is meant to be a syntax error these days. <masak> jnthn: why? <masak> it's just out of bounds. <jnthn> std: @foo[-1] <p6eval> std 25906: OUTPUT«##### PARSE FAILED #####Obsolete use of [-1] subscript to access final element; in Perl 6 please use [*-1] instead [...] <amoc> from http://perlcabal.org/syn/S09.html#Negative_and_differential_subscripts <masak> oh. <amoc> it says: "Using a standard index less than zero prepends the corresponding number of elements to the start of the array and then maps the negative index back to zero"? <jnthn> masak: Because STD.pm says so. But yes, you can declare an array with different indexes too... <jnthn> So I'm not sure what'd happen there. <masak> shall I report this as a rakudobug? <jnthn> You can. We're inconsistent with STD.pm there, so it's probably worthy of a ticket. <masak> someone put together an example for STD with a different-indexes array, and see what it says! :) * masak submits
