| // Lexer and parser for expressions of the form: | |
| // | |
| // f(g(h("foo"), i(3, "bar"))) | |
| // | |
| // Note that while it does understand strings and numbers, it doesn't | |
| // do binary operators. We can do those via functions if needed, ala | |
| // add(x, y), sub(x, y), etc. | |
| // | |
| // Caveats: | |
| // * Only handles ASCII. | |
