I think your new addition above could be modified lightly like:

+@code{pk} improves on using @code{write} directly because it enables
+inspection of the state of code as it runs without breaking the normal

With the above change, I'd like to see this in the Guile manual :-).
Would you be able to send an easily applicable v3?  Then the last step
