I'm not sure what this test, tests for?

in order to have an analogue to (chunk, enc, cb) => { } we add an encoding property for cases where transform streams behave differently depending on the encoding.

I don't think this is taken into account in Readable.from and since we are doing objectMode I'm still unsure what the semantics here should be. I need to think about this a bit more unless someone can clarify?

@davidmarkclements: I don't think this test is needed. Returning a non promise is fine?

@davidmarkclements Moved invalid arg check to Readable.from.

@davidmarkclements I've updated to include type checks |

@davidmarkclements: I don't understand the encoding test or implementation. Where else in streams related code do you see anything like this? Do you think you can explain it's purpose? |
