I respectfully disagree that this is a 'useful' distinction. My main
point is consistency. To me, it's counterintuitive to have two
Bioperl classes, both which inherit Bio::Root::Root, use two
different syntaxes for any parameters passed to the constructor, even
if some are 'program' parameters. It's also not consistent with
StandAloneBlast or RemoteBlast, both which are considered bioperl-run
modules even though they are in core, and both or which use dashed
parameters (StandAloneBlast actually allows both). In fact, it isn't
consistent within bioperl-run itself.
Bio::Tools::Run::EMBOSSApplication uses dashes for parameters in a
Okay, judging by the previous examples, 'consistency' isn't a word I
would use to describe bioperl-run as a whole (back to Jason's 'cat-
herding' analogy). It would be easier to let it slide for now,
especially since changing them would be a serious pain, not to
mention an API issue. But shouldn't there be some consistency?
And what about new modules? Do we follow the historical (possibly
confusing) 'dashless' route, or use the core-like dashed approach
(thus breaking from the other run modules)?

I'll allow for both, ala StandAloneBlast. Doesn't hurt to be safe. ; >
Have fun at the hackathon!
