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,
