Hmm.. the "Bacon.Bus does not plug after end(), second variant" test is still failing.

[raimohanska]

To me it seems that the test is wrong:

  it "does not plug after end(), second variant", ->
    failed = false
    busA = new Bacon.Bus()
    busB = new Bacon.Bus()
    busB.onValue(-> failed = true;)
    busB.plug(busA)
    busA.push('foo')
    busB.end()
    expect(failed).to.equal(false)

You plug busA before ending busB, so it's correct to pass the "foo" event through, right?

Ah seems, I swapped the lines when "cleaning up the mess".

Fixed.
