Oops... I just noticed that this was on my "to reply" list.  The only issue with this is that specific Error objects would all be siblings of Exception--they wouldn't have a common parent to identify them as Errors.  I thought it might be handy to have a common parent in case we want to treat Errors differently at some point, though I guess we could just as easily assume that everything that isn't an Exception is an Error and exclude that way.  It just means slightly different logic:

try {}
catch( Exception e ) { throw e; }
catch( Throwable e ) { /* handle error */ }
