my understanding is that you want something like that :
--
$arch = ArchiveFile.new('filename')
--

with $arch being nil if filename doesn't exist.

if i'm right then you're going to have to test if it's nil before doing
anything with it ...
and that's not really more readable than the rescue code.

--your(i think) idea--
if ($arch = AchiveFile.new('filename') ) then
    ...do sg...
else
    ...error...
end

--with rescue--
$arch = ArchiveFile.new('filename') rescue ...error...
....do sg...


my 0.02?

PS: maybe i've done some big mistakes :) i'm quite new to ruby.
