1834 :: How to impl a lend semantics?

  I mean

  var a = unique 0
  var b = a # compile error, a is unique
  var c = consume a # ok, a is consumed
  var d = consume a # compile error, a is consumed
  Run

  All I have known is to use pragma tag and macro to limit variables' access. But it seems not enough to let the compiler know the origin var 'a' has been consumed. Forgive my poor English :)
