my @param = $q->param(); @input{@param} = map $q->param($_), @param;
I couldn't be bothered to Benchmark it but I suspect this is going to be the most efficient or at least a very competitive variant, especially so if the number of parameters is substantial.

Update: Or maybe this:
my @param = $q->param(); @input{@param}=(); $input{$_} = $q->param($_) for @param;
Finally, this leads us to another variation which I like best:
@input{$q->param()}=(); $input{$_} = $q->param($_) for keys %input;
Between the latter two, I'm not sure which one will perform better.

Makeshifts last the longest.

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.
