in reply to Re: RFC US Region Module
in thread RFC US Region Module

If I leave it OO don't I avoid the issue of the function name collision you mention? While I agree there is no current or compelling reason for this module to be OO it does seem to work easily enough to provide the functionality I need. Would I see benefits from it being non-OO?

The DATA read has been moved outside of the new since that was the wrong spot for it and subsequent object creations would have resulted in an empty hash ref being assigned to $self.

Of the names I felt the Geography namespace would be best, but I am still struggling with the Census::Regions / Regions::Census issue for these reasons:

  1. Geography::US::Regions would leave the name space open for additional Region separation specific modules each named for their source, as in this case Census
  2. Geography::US::Census seems limiting to me because the number of Geography based concepts that would deal with Census seem limited.

Thanks for the feedback.

    Perl uses packages to implement OO but packages don't necessarily imply OO. Packages provide namespaces that help avoid function and variable name collisions. Those functions don't necessarily have to be written in an OO fashion, though.

    90% of every Perl application is already written.

    The collisions are already avoided by writing something like Geography::US::Census::Regions::state, which is admittedly clumsy. You can use alternative exporters such as Exporter::Tidy to provide your users the option to choose a prefix or alias of their preference for the exported functions. OO is the wrong tool here.
