Do you think I should make a pull request for phobos inclusion?

A timer would be cool. It would be nicer (though more complicated to
implement) to support multiple timers running in one thread. Mono had
such an implementation in C#, but we can't use it of course (LGPL).

And we should probably try to support a generic API for timers (either
templates, isTimer!T, etc or classes+interfaces) as EventLoops (libev,
libevent, glib, windows sure has some as well) provide more efficient
ways to implement timers.

As for the event struct: I'm not sure, as a implementation detail it's
fine, but as a public API I'm not sure.

You would have to implement the timer completly different, it uses a 
Condition Lock (core.sync.cond) to wait, except you can wait on multiple 
locks at once and return when one of these is notified.

 templates, isTimer!T, etc or classes+interfaces) as EventLoops (libev,
 libevent, glib, windows sure has some as well) provide more efficient

This is true, but you don't always want/need a Event Loop.
