Description

There should be an option to show onward calls, e.g. if map f (x:xs) calls map f xs that should be presented as an onward call, which is possible since debug tracks which f is being passed. Using this onward call information can build a call stack, giving a more traditional style of debugger.

Contributor guide

Research direction
Investigate how `debug` tracks function calls and identify where to store onward call information. Look at the existing tracing mechanism to attach parent child relationships and build a call stack for display.
