Right, the confusion is that there is a DateTime::Span class, and
I'd expect DateTime::Format::Span to take an object of that class
and format it.
However, your module only operates on durations. Even more
confusingly, it offers a "format_duration" method which only accepts
a single duration, which is _not_ a span.
This really is not a good name for your module, because of this
reason.
Ah I see, that does make sense. I see what he means now. I'm not sure
how I didn't see that. I'll take it offline until I can get a better
name.
Some of the information you define in the locale modules does exist
in CLDR, notably singular versions of things like "day", "month",
etc.
if you add the singular and plural information to the auto generated
DateTime::Locale I'd be happy to use it instead
CLDR also includes formats for doing things like formatting a span
based on the "greatest unit of differnece" between two dates. It's
rather complicated, so I haven't implemented it yet. Basically, it
lets you format something intelligently so you get "Jan 10-12" vs
"Jan 10 - Feb 10".
cool
