Hmm, I've not decided yet.  Here's the list of options:

  * rescue IOError in var

    Current parser accepts this syntax.  No new reserved word
    introduced.

  * rescue IOError into var

    More descriptive than 'in'.  Introducing new reserved word, which
    raise backward compatibility problem.

  * rescue IOError => var

    No reserved word introduced.  Symbols may ambiguous.

  * exception

    This option introcudes new global function `exception' which
    returns the $! value.  No reserved word introduced.  I think this
    simple way.

  * Exception::last

    This may more descriptive than mere `exception'.  But I feel it's
    too long to type in.  You know I'm lazy.  Notice `ruby' is 2
    letter shorter than `python'?
