I am wondering: is it too bad to use the debugger as an in...

For the past couple of hours I've been trying to format a MySQL timestamp using DATE_FORMAT and it doesn't do anything!

I would like to write a Perl function that gets a GFF3 filename and a range (i.e. 100000 .. 2000000). and returns a reference to an array containing all names/accessions of genes found in this range. I guess using bioperl will make sense, but I have very little experience with it. I can write a script that parses a GFF3 by my self, but ...
