I certainly agree with the first part, slightly reworded: we should strive to generate fewer exceptions that we have to catch.

I disagree with the second part:  being able to condense four lines of code (1 for try, 1 for except, 1 for the attempt, and 1 for recovery) in to one line of code seems like a win.  I know I find it frustrating when my choice is between the 4-line boiler-plate try/except, or an equally verbose and ugly multi-line non-exception generating stanza.

Anyway, my two cents worth.  If you collect them all for this subject I think I owe you a dime.  ;)
