you need to design a custom interface for each major resolution. Add some scaling factors in and you might be able to cut it down to 5-8 different interface designs. Further, the UI means "User Interface" and includes a lot more than just the resolution - you can't count on a touchscreen, full keyboard, or even softwa...

you need to think recursively, for example, using your sample string, ``` 1+11*5 ``` to do this manually, you would have to read the `1`, then see the plus and start a whole new recursive parse "session" starting with `11`... and make sure to parse the `11 * 5` into its own factor, yielding a parse tree with `1 + (...

you can mix and match other libraries *all in the same code*. (Embedding a parsing language like this in a language other than Haskell results in loads of syntactic cruft, by the way. I did this in C# and it works quite well but it is not so pretty and succinct.) **Notes:** [1](http://docs.garagegames.com/tgea/offici...
