Is there a way to undo a `defvaralias' from Lisp?

Meaning a hypothetical function `unalias' so that after

  (defvar foo nil "Foo")
  (defvaralias 'bar 'foo "Bar")

  (unalias 'bar)

`foo' is untouched, but everything about `bar' forgotten.

I haven't found one, but then I haven't been searching very
thoroughly.
