Given the power of any computer (even those 30 years old), it's enormously powerful to be able to drop one segment of a pipe-chain and look at the output. Funny that I'm facing a similar issue now that some of the server world is going Javascript: "console.log(X);" doesn't necessarily tell you the whole story about X. Exchanging objects is 14% too complicated and anything more than 0% too complicated is too complicated.
