[Bioperl-l] What's wrong with the script about module Bio::SeqFeature::Gene::GeneStructure

But I think an "mRNA" feature should have exons. For example:

     mRNA            complement(join(1031434..1031901,1031940..1032269,

Such mRNA should have 4 exons and 3 introns, right? And I just want to
calculate the lengths of every exons and introns quickly.

Besides, in the document of module Bio::SeqFeature::Gene::GeneStructure,
it writes like these:

@exons = $gene->exons();
@introns = $gene->introns();
@utr_sites = $gene->utrs();

Then where does the object "$gene" come from? I've searched through all
the google sites but found nothing.
