[Bioperl-l] proposed patch to Bio/Annotation/SimpleValue.pm

I got an error upon incrementing the score of a
Bio::SeqFeature::Annotated 

Operation "+": no method found,
	left argument in overloaded package
Bio::Annotation::SimpleValue,
	right argument has no overloaded magic at ./myscript line xxxx.

It turns out that Bio/Annotation/SimpleValue overloaded "" and eq but
did not provide a fallback for other operators.

The following patch should fix that.

Any Objections?
