Re^2: Password Program

If this statement is run with warnings asserted, what will Perl say about the statement?

Unfortunately, nothing... the "Scalar value @wrongPasswords[4] better written as $wrongPasswords[4]" warning you're probably referring to doesn't seem to get triggered by the assignment.

$ perl -wMstrict
my @foo;
@foo[3] = "bar";
print @foo[3], "\n";
__END__
Scalar value @foo[3] better written as $foo[3] at - line 3.
bar

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.` [download] Je suis Charlie.	[reply] [d/l]

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]
