[Templates] Getting keys from a hash

[Mark Mills]

Maybe, rather than rolling your own hookup to CGI, you should look at 
the CGI plugin for TT:
http://template-toolkit.org/docs/modules/Template/Plugin/CGI.html

It has code to avoid the exact issue you ran into. One extra method that 
does what you need.


      METHODS

    <#>

    In addition to all the methods supported by the |CGI| module, this
    plugin defines the following.


        params()

    <#>

    This method returns a reference to a hash of all the |CGI|
    parameters. Any parameters that have multiple values will be
    returned as lists.

    [% USE CGI('user=abw&item=foo&item=bar') %]
    [% CGI.params.user %]            # abw
    [% CGI.params.item.join(', ') %] # foo, bar
