This is also related to RT #62948, where null values appear in arrays and other 
aggregates.  Instead of adding a bunch of "is this value null" checks

undefs at the appropriate points.

Is it feasible to catch all "Null PMC access" exceptions at the top-level, 
promote PMCNULL to Undef (or Failure) and resume from exception?
