Currently we have both inline and transparent. It is expected that we will drop inline in the future.
- avoid computing owner of NoSymbol
This was the enclosing class instead of the method containing the annotation. Fixing this is surprisingly hard.
- premature optimization, we can just inspect the owner chain, - if we need it, it should be an automatically updated cache
The idea is that such annotations create some proper subtype of the type they annotate. Hence, they cannot be stripped away like normal annotations are.

Commit Messages
We want to keep history, but for that to actually be useful we have
some rules on how to format our commit messages (relevant xkcd).
Please stick to these guidelines for commit messages:
- Separate subject from body with a blank line
- When fixing an issue, start your commit message with
Fix #<ISSUE-NBR>:- Limit the subject line to 72 characters
- Capitalize the subject line
- Do not end the subject line with a period
- Use the imperative mood in the subject line ("Add" instead of "Added")
- Wrap the body at 80 characters
- Use the body to explain what and why vs. how

Based on #4622. We are trying to add a kind of annotation that can be used as a carrier for TypeOf types.
