Perl variables/arrays/hashes are created out of whole cloth - attempt to handle some of these by checking for a reference to a var/array/hash before it's defined and inserting a definition/initialization. For example:

$options{this} = 1;

creates the %options hash, then adds one key/value to it.

$i++;

creates the variable i, then adds 1 to it.

The generated python code gives errors because these variables are undefined.
