heh. for some definitions of "poorly".

Problem:
Trying to allow lazy maintenance of multiple interface widgets, frinstance Receipt::DoubleA, Receipt::TextOnly, Receipt::BannerAds, etc

at a level above the widgets, we have an AUTOLOAD that allows us to call $ui->Receipt->build(%args), and it will use the Receipt parent class or choose the right subclass based on external criteria.

The problem is, for example, that we might have a Text subclass under Receipt, but not have one under Error.

In that case we could

1) mandate the creation of an "empty" subclass for every widget for each new interface, with at minimum an @ISA statement

2) descend into some inelegant evalling or -e testing at some level (perhaps in the parent widget class), or

3) see if there might be a way to check from upstream if in fact there was a Text interface for a particular widget before trying to AUTOLOAD it.

4) accept new and novel suggestions from perlmonks, et al.

Ideally, without keeping a separate registry hash of available interfaces, of course ;)

As you noted, perhaps too tricky. The extenuating circumstances of how we got here are lengthy and boring.
