Question

For example, say I want to do this:

{
  :mytime => times[:mytime]
}

There is a bit of repetition here, is it possible to just do something like { :mytime => times[$_key] } (made up syntax)?

Answer 1

The short answer is: no, there’s no syntax that does anything like that. Without more context about what you’re actually trying to do, there isn’t really a good longer answer. Still, I’ll try to be a little more useful. If you’re really worried about repetition, you could do something like:

h = {}
[:mytime, :yourtime].each do |k|
  h[k] = times[k]
end

For only a few keys, I can’t see that being worth it, personally.
