With the introduction of (ice-9 exceptions), SRFI 35 has also been
rebased on top of it.[1]

Personally, I’d rather stay with the well-established interface provided
by SRFI 35.  It seems like needless churn to rewrite all current
exception handling to drop down one layer onto Guile-specific
infrastructure.
