| * - Traverse resulting syntax tree, trying to apply a set of visitors to each |

| * visitor can process a given node. |
| * |
| * - Visitor is responsible for code generation for a given syntax node. |
| * Generated code is stored in state.g.buffer that is passed to every |
| * visitor. It's up to the visitor to process the code the way it sees fit. |
| * All of the current visitors however use both the node and the original |
