I agree completely. Swissknife (lazy parsing of Swiss-Prot) was mentioned
here yesterday. We could use something similar for GenBank/EMBL. The code
for Swissknife was quite extensive but, really, so is SeqIO::genbank!
I also wanted to see how much using bioperl's _readline() method slows
things down (my guess is not too dramatically, but for 20 MB files it may be

We can't promise anything! If you want, add a bit to the Bioperl release
I would hold that request off until post-1.6. Lots of other priorities
