I see it as quite similar. The proposal is to lift conditions out of the 
body of a compound statement and put them in the header.

There is always the option to catch everything in one except statement 
and conditionally process or re-raise as desired. Having all exceptions 
be instances of named subclasses of one baseclass makes this easier than 
when exceptions were strings.
