Cheers for that.

I've found a small bug in the original patch that produces unexpected 
results - simply forgot a return statement.

I've had a think about this, and came to the conclusion that it would 
be more consistent if error_on_undef_var lived with the other 
configuration params - it can still be set as a global here, and now 
other packages can rely on it.  As such, I've moved it up to the Petal 
package, pod & all.

Patch for both of these against 0.96 attached.
