Then please, implement a benchmark that exhibits the savings you are concerned about.

#! perl -slw use strict; use Benchmark qw[ cmpthese ]; our %hash = 'aaaaa' .. 'dzzzz'; cmpthese 1, { a => q[ my @keys = keys %hash; my @vals = values %hash; my $x; $x = "$keys[ $_ ] :: $vals[ $_ ]" for 0 .. $#keys; ], b => q[ my( $k, $v, $x ); $x = "$k :: $v" while ( $k, $v ) = each %hash; ] }; __END__ s/iter a b a 3.06 -- -41% b 1.79 70% --

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

Title:
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.
