* reading from streamsKartik K. Agaram2021-07-034-22/+152
| | | | | | The Mu shell has no string literals, only streams. No random access, only sequential access. But I've been playing fast and loose with its read pointer until now. Hopefully things are cleaned up now.

| | | | We just need to support unary operators.

| | | | | | | | | | | | | | | | | | | | | Like parenthesize, I'm copying tests over from https://github.com/akkartik/wart Unlike parenthesize, though, I can't just transliterate the code itself. Wart was operating on an intermediate AST representation. Here I'm all the way down to cells. That seemed like a good idea when I embarked, but now I'm not so sure. Operating with the right AST data structure allowed me to more easily iterate over the elements of a list. The natural recursion for cells is not a good fit. This patch and the next couple is an interesting case study in what makes Unix so effective. Yes, you have to play computer, and yes it gets verbose and ugly. But just diff and patch go surprisingly far in helping build a picture of the state space in my brain. Then again, there's a steep gradient of skills here. There are people who can visualize state spaces using diff and patch far better than me, and people who can't do it as well as me. Nature, nurture, having different priorities, whatever the reason. Giving some people just the right crutch excludes others.
