I've personally started on this effort yesterday, writing about error
handling in Guile.

I've finally read your post
It's nice that it clears the distinction between old forms and new ones
I'd like to have continuable exceptions covered, though
Those are the main departure of Guile from more widespread exception handling solutions and as far as I can tell something similar is available only in Common Lisp so drawing experience/intuition from other languages is more difficult/rare
