* high frequency FREQ can be optimized by precomputing larger steps of INTERVAL
* include this in docs:
http://www.w3.org/2001/sw/Europe/200210/calendar/vocab_usecases.html
http://www.imc.org/ietf-calendar/mail-archive/msg00623.html
* optimize yealy/monthly + interval + byday
- uses intersection with "all days"
* "byday -2 friday"
- test overflow
- need some 'interval' and 'dtstart' tests
* the implementation of 'select' in Set::Infinite is incomplete
and doesn't have the 'last' attribute. -- should be implemented!
Note: this is not a problem because it is only used in 'count',
which generates finite sets.
* finish importing Date::Set RFC2445 recurrence tests
* bysetpos
- use some kind of memoization
* byweekno - test with 'daily'
* no tests were made defining recurrences without dtstart.
* the effect of 'count' on a recurrence without dtstart is not defined.
the effect of count == 0 is not defined.
* no tests were made using datetimes with timezones.
* mixing positive and negative arguments in the same list
might give wrong results is the numbers are big enough
to cause the datetimes to interleave.
- split in two recurrences and join with 'union'
* some arguments are not checked for overflow,
such as byyearday.
