Swap Channel input with output?

[trusktr]

This is confusing:

channel.output.put(x)
var data = channel.input.take()

If we're using words like "input" and "output" to describe parts of a channel, It seems like we'd put something into the input of a channel, and take something out of the output of a channel, so in that case, it'd make more sense as

channel.input.put(x)
var data = channel.output.take()

Isn't it more intuitive that way? Or did I missunderstand something about the concept?
