Not sure I’m doing the right thing here… setting `debug-on-entry` for
`gnus-summary-prepare-exit-hook` and stepping through I see this.

  Debugger entered--returning value: nil
  #f(compiled-function (&optional now) "Expire all articles that are marked as 
expirable in the current group." (interactive nil) #<bytecode 0x15590511b8b9>)()
* apply(#f(compiled-function (&optional now) "Expire all articles that are 
marked as expirable in the current group." (interactive nil) #<bytecode 
0x15590511b8b9>) nil)
* gnus-summary-expire-articles()
  run-hooks(gnus-summary-prepare-exit-hook)
  apply(run-hooks gnus-summary-prepare-exit-hook)
  gnus-run-hooks(gnus-summary-prepare-exit-hook)
  gnus-summary-exit()
  funcall-interactively(gnus-summary-exit)
  call-interactively(gnus-summary-exit nil nil)
  command-execute(gnus-summary-exit)

And going a bit deeper…

  Debugger entered--entering a function:
* apply(message ("Expiring articles in %s..." "nnimap+gold:Junk Email"))
* gnus-message(6 "Expiring articles in %s..." "nnimap+gold:Junk Email")
* gnus-group-expire-articles-1("nnimap+gold:Junk Email")
* nnvirtual-request-expire-articles((13) "vg-test" "^nnimap\\+gold:Junk Email$" 
nil)
* gnus-request-expire-articles((13) "nnvirtual:vg-test")
* #f(compiled-function (&optional now) "Expire all articles that are marked as 
expirable in the current group." (interactive nil) #<bytecode 0x15590511b8b9>)()
* apply(#f(compiled-function (&optional now) "Expire all articles that are 
marked as expirable in the current group." (interactive nil) #<bytecode 
0x15590511b8b9>) nil)
* gnus-summary-expire-articles()
  run-hooks(gnus-summary-prepare-exit-hook)
  apply(run-hooks gnus-summary-prepare-exit-hook)
  gnus-run-hooks(gnus-summary-prepare-exit-hook)
  gnus-summary-exit()
  funcall-interactively(gnus-summary-exit)
  call-interactively(gnus-summary-exit nil nil)
  command-execute(gnus-summary-exit)

Sorry if that wasn’t what you meant.
