What about using guards?

  try
    -- attempt code
  catch e if is(e, Engine.DivideByZeroException) then
    -- catch Engine.DivideByZeroException
  catch e if is(e, Engine.Exception) then
    -- catch Engine.Exception
  end

I think the syntax is still sufficienty concise.

If you follow this path, you don't have to force a particular object
system on users.
