Makes sense! So the precendence is like this?

  1. Use explicit binding from Global.tmProperties.
  2. If none found, use first line match.
  3. If none found, use file types (extension).

If more than one bundle claims a file type by extension, is it “longest 
match wins“? (The RSpec bundle uses `_spec.rb` which seems to take 
precedence over Ruby's `rb` even for empty files.) And what happens if 
two bundles claim the exact same extension? (Both Ruby and Rails claim 
`rb`, and apparently the Ruby bundle “wins”.)

Great, this has already proven itself very helpful. Thanks!

Cool – didn't know that it's possible to combine wildcards like this!
