Subject: rescue syntax


I know it's Does anyone else find themselves trying to abbreviate error handling code as follows?

From:
if( expr )
  begin
    # do stuff
  rescue
    # oops
  end
end

To:
if( expr )
  # do stuff
rescue
  # oops
end

Would the option of attaching rescue conditions to arbitrary code blocks be desireable? 
For methods, I'd imagine something like the following

def method
 # method logic
rescue
 # oops, bad logic
end

and maybe

array.each do |e|
  # process e
rescue
  # bad process
end

I haven't really thought through all the different constructs.  In addition, I don't know
how this might affect the clarity of code.  I guess it could get somewhat obscured if code 
starts looking like:

if
  # blah
rescue
  # blah
else
  # else logic
rescue
  # else-rescue logic
end

What do other people think?
