Re: Scalar value @scores_sorted[$i] better written as $scores

Your version is canonical in perl6.

Perl 5 is stricter - it insists on Scalars being represented by the "$" sigil - in your case, printing ONE score item is a scalar, so perl (5) expects a "$".

Syntactic sugar causes cancer of the semicolon. --Alan Perlis

Perl 5 is stricter - it insists on Scalars being represented by the "$" sigil - in your case, printing ONE score item is a scalar, so perl (5) expects a "$". Partially right. In this case, a one element list is printed. I find the warning highly annoying. It's a case where Perl knows what I mean, does what I mean, and still thinks it's Python, insisting in one true way of doing things. Despite it being the syntax of the future.	[reply]
