( [id://3333]=superdoc: print w/replies, xml ) Need Help??
here is one code
perl -e "%package = ( 'zips' => {1,2,3,4} ); print %package->{zips};"
other code
perl -e "%package = ( 'zips' => {1,2,3,4} ); print $package{zips};"
both the one liners print

HASH(0x23bbe4)
but when I enable warning(-w) the former produces

Using a hash as a reference is deprecated at -e line 1.

I thought only the later should work, the former should fail, but it is also working but outputs along with a warning. can anyone tell me what happens if I do like %package->{key} considering the above example.

Use:  <p> text here (a paragraph) </p>

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).
