I figured out a way to do this without the explicit list. Check it out:

```ruby
::Template.instance_variable_get('@_cache').each do |path, tmpl|
  @views[(File.basename path)] = tmpl
end
```

I'm going to see if the Opal project will consider exposing the data in `@_cache` via the public API so that we don't need this hack. For now, though, it gets the job done.
