  ```raku
  sub callframe(Int:D $level = 0)
  ```
  
  Returns a `CallFrame` object for the given level. If no level is given, the default level is 0. Positive levels move up the frame stack and negative levels move down (into the call to `callframe` and deeper).
  
  Returns [`Mu`](/type/Mu) if there is no call information for the given level. Negative levels may result in an exception.
