$set->length (sound like it could be a DT::Duration between the first
and last)
$set->elements (sounds like a clone of as_list)
$set->count (possible, though could it be a count of something else?)
$set->number_of_elements (long, but self explainitory)
So what does it return? I figure it returns
1 + $#{$set->{set}{list}}
when it can, and it returns
$DateTime::INF
when it can't.
It would also be good if it could accept a span like as_list does.
Then if there is an infinite set (Say a set of Friday 13ths), we can get
the number of them in a particular span. Without the span parameter it
returns the count of the whole set or it returns INF.
Cheers!
