[Wtr-development] automatic waiting?

I've also been thinking about implementing that too. The downside is slowing
things down significantly when something goes wrong, or when debugging -
sitting around waiting for error messages to finally show up is annoying. I
think it'd be good, provided two things.
1. it's configurable, so users can turn it off or adjust the amount of time
2. the default is short, not more than one second. waiting 5 seconds in irb
whenever I try to access a nonexistent element would annoy me a lot. 1
it's not enough for AJAX stuff, but the user can set this to longer as
needed, or use an explicit wait_until.
I also think that this should happen in #initialize, and not in
#assert_exists - it should only happen once at the beginning, not whenever
you try to do anything with an element. that conflicts with watir's lazy
locating, though. I think that should change too, personally - just seeing
'located=false' when inspecting an element is not useful. (vapir tries to
locate in #initialize and shows 'exists?=false' on elements that don't
exist, doesn't ever just say "I don't know, I haven't tried to find it
