How about even more simply and efficiently using methods provided by CGI.pm ...

my %input = CGI::Vars;

The above performs the same as your proposed code but ties your array in with that used internally within CGI.pm for the storage of CGI parameters.

Of the proposed code samples provided however, map and grep would be poor choices as, in the examples given, these are being used in a void context, the return values built and returned by these functions discarded. With regard to for and foreach, according to perlsyn, foreach is merely a synonym for for, the choice between the two representing a balance for the programmer between readability and brevity.

Title:
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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
