[Bioperl-l] hash key for SeqFeatureI

Hi Bioperlers

I'm adding hash_key methods to various classes (part of my work in 
making Bioperl object comparable), and for SeqFeatureI, I was wondering 
whether the following is adaquate: primary_tag(), display_id(), 
location->start(), location->end()? The point of a hash_key() method is 
to return a string which uniquely identifies the object - i.e. if two 
hash keys are identical, then the objects are equivalent.

And related to this, where is the strandedness of Bioperl SeqFeatures
