Time.every improvement

[kuznero]

Does it make sense to improve current every : Time -> (Time -> msg) -> Sub msg to every : Time -> (Time -> Maybe msg) -> Sub msg, such that event is fired not precisely every N something, but also does that based on some predicate that will be possible to implement in Time -> Maybe msg lambda?

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.

It may make sense, but any design like this would need to be motivated by practical examples. If you have some of those, that can make a stronger suggestion. I'd recommend trying to refine the idea on Elm slack or the elm-discuss mailing list and opening a new issue if you feel you have compelling evidence.

@kuznero, there are related questions for other "subscription generating functions". So it might be useful for you to have a look at:

• API change suggestion: make the downs/ups/presses function selective via Maybe elm-lang/keyboard#7

as well as at two existing mailing list threads (referenced over there):

• https://groups.google.com/forum/#!msg/elm-discuss/u-6aCwaJezo/fu-HMPy6CQAJ and
• https://groups.google.com/forum/#!topic/elm-discuss/Ud7WzAhRsqE
