This example:
var node = (new webkitAudioContext()).createGainNode(); node.connect(node);
doesn't throw in Chrome dev. Chris, how does Webkit handle cycles?

I agree that checking for cycles on every connect() could be a performance
killer. Depending on how the author constructs the graph, it could make
graph construction an O(N^2) operation.

[Of course I agree with you that MSP's solution is a good one :-).]

Filed ISSUE-77.

“You have heard that it was said, ‘Love your neighbor and hate your enemy.’
But I tell you, love your enemies and pray for those who persecute you,
that you may be children of your Father in heaven. ... If you love those
who love you, what reward will you get? Are not even the tax collectors
doing that? And if you greet only your own people, what are you doing more
than others?" [Matthew 5:43-47]
