Thoughts
Like I understand that in the universe that we live it is considered commonly acceptable that the "correct" behavior of standard in is to
behave like a file. But in this case, as in many cases, I would like to treat it like a string, and I don't understand why that's not an option. Yes I understand what the means and what that entails and I want a version of `Readable.toString()` that blocks until the stream has been read into a string because 99% of the time that is what I want to do with readable streams.
