Description

The XS argument processing code for Lucy's Perl bindings is supposed to detect
when required parameters were not supplied by the user and throw an
informative exception. Sometimes, it does not, resulting in invalid input
being passed to core functions. Typically, this would be a missing required
object, resulting in a NULL-deref by the core code.
