At the interpreter debug hook level, there is the notion of a return
event at the moment that a function or method call returns. We show the
underline rather than the solid block when the current debugger event is
a return event rather than one of the others (call event, line event,
and exception event).
Whenever the underlying is shown, you can hover the mouse over the word
"return" and wing will show the value that will be returned from the
function or method.
