I'm not sure what you mean here exactly. The original assert() can be
written as:
function assert(cond, err)
  if cond then return cond
  else error(err or "assertion failed")
  end
end
So you can write things like foo = assert(getFoo()). As long as any
replacement assert() you write returns cond like this, you can do the
same. Is this what you meant by chaining?
