Here's a way of doing it -- but it uses package variable (i.e. globals) and, of course, you have to fully qualify them. (Or else declare them with "our").

#!/usr/bin/perl use strict; use warnings; my %data = ( "blah"=>1, "boo"=>2, "hoo"=>3 ); # assign each key to a package variable of the same name foreach (keys %data) { no strict 'refs'; ${"main::$_"} = $data{$_}; } # end-foreach # note, this causes a "used only once" warning as the symbolic referen +ce # above doesn't count. Irrelevant for this example. print $main::blah; exit;

It's still unclear what this gains you. Anytime you're resorting to symbolic references or package variables, it should be a warning sign that something isn't well thought out. There are relatively few areas where it makes sense (e.g. writing modules which manipulate the symbol table of the package that uses them.)

Title:

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.
