[Catalyst] InstancePerContext doesn't work in schema

[Steve Kleiman]

Hey Tomas. Thank you very much for responding.

The challenge I've got is that sometimes I want a schema object to act on a date or time. However to do that properly, it needs access to the current user's time zone and locale. I gather you're suggesting I just pass in the time zone and locale to the object every time. Cool. I can refactor that.

How about handling something as straightforward as getting debug text within a Schema to the console, e.g.,
$c->log->debug("hello")

What's the recommended procedure for debugging outside the Controller?

Thanks again.
