Re^3: Password Program

Well, yes, it seems to be trigerred by the assignment:

$  perl -wMstrict -e 'my @foo;
 @foo[3] = "bar";'
Scalar value @foo[3] better written as $foo[3] at -e line 2.

Aha! perl5200delta: The warning "Scalar value @hash{foo} better written as $hash{foo}" now produces far fewer false positives. In particular, `@hash{+function_returning_a_list}` and `@hash{ qw "foo bar baz" }` no longer warn. The same applies to array slices. [perl #28380, #114024] The commit is 429a25554a6. The argument for this change was that something like this is useful: `use warnings; use strict; my @foo; $foo[0] = "abcd"=~/b(.)/; # scalar context @foo[1] = "abcd"=~/b(.)/; # list context print "{$_}\n" for @foo; __END__ {1} {c}` [download]	[reply] [d/l] [select]
