Vergiss es. Ich hab das hier ueberlesen:

Many people want to fetch the entire parameter list as a hash in which
the keys are the names of the CGI parameters, and the values are the
parameters' values.  The Vars() method does this. Called in a scalar
context, it returns the parameter list as a tied hash reference.
Changing a key changes the value of the parameter in the underlying CGI
parameter list.  Called in a list context, it returns the parameter list
                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
as an ordinary hash.  This allows you to read the contents of the
^^^^^^^^^^^^^^^^^^^
parameter list, but not to change it.

Sorry,
