[Bioperl-l] Re: sub_Location in Bio::Location::Simple?

[Jason Stajich]

I'd rather create a new method, something like:
each_Location().

This can be implemented as a recursive method to handle the case when
split locations contain other split locations.

I don't want to make Simple locations explictly act like Split locations
with a single loc since that defeats the purpose of separating the
interfaces.

Other people may have input?
