Sorry, I may have missed this in the previous thread, but why an inline
rescue clause is not enough?

i.e.

 while (line = gets && line.chomp)
  foo = (bar && bar.baz && bar.baz.quuz) || default # bar might be nil, so
 might bar.baz and bar.baz.quuz

could be

 while line = gets.chomp rescue nil
  foo = bar.baz.quuz rescue default 
 end 

I admit I have a strange feeling about a raising loop condition.. but
something like the second line I wrote many times. 

This is slightly longer and gives you a little bit less control,
but I think that complex one-line flow control may be a bad thing.

Just my two cents, obviously.
