Re: more srfi-12 rationale?

This page is part of the web mail archives of SRFI 12 from before July 7th, 2015. The new archives for SRFI 12 contain all messages, not just those from before July 7th, 2015.

I agree with Per and Dave: exceptions are nice but conditions
can be dropped / moved to another SRFI. The best abstraction
to recognize particular kinds of values is a predicate; specifying
exact representation, no matter how "normal" it is, just reveals 
unnecessary implementation details.
