Why doesn't Perl have a warning for the [@hash{@array} = 'foo'] case?

I would say because an empty hash slice assignment | index list is a perfectly valid thing. It's equivalent to
    $hash{$_} = 'foo' for @array;
which also does not (and should not) warn.

c:\@Work\Perl\monks>perl -wMstrict -MData::Dump -le "my %hash = qw(a 1 b 2); my @array; @hash{@array} = 'foo'; dd \%hash; ;; $hash{$_} = 'foo' for @array; dd \%hash; " { a => 1, b => 2 } { a => 1, b => 2 }

Give a man a fish:  <%-(-(-(-<

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
