 * Notable issues:
 * * if a story is all object syntax, then it won't have
 *   a storySource at all. That's likely a limitation of source-loader.
 * * If a story name is very long, story-loader's handling can get weird
 *
 * TODO: some notable naive approaches here. Could parse AST to get
 * the default export, to automatically include assignments to stories, or
 * to better parse story objects.
 *
 * TODO: Some of this might be suitable contribution to storysource, but
 * the goals there often different, e.g. to show how to use a component
 * whereas here we're showing how to build stories.
 *
 * TODO: ideas include-render, include-template, include-region
 *
 * All comments start with `// story-code` or with `/*` or `/**` style
 * single line comments. So `// story-code @end SomeComponent @include-default`
 * for example.
 *
 * ## Available commands:
 * * `@end`: end the previous story's code block. Note, this is works across
 *   stories such that any story which does not specify its end which begins
 *   before this use will end at this point. Use named end's if you need specificity
 *   ```ts
 *   const SomeStory: ComponentStory<typeof Comp> = (args) => <Comp {...args} />;
 *   SomeStory.args = { prop: 1 };
 *   // story-code @end
 *   ```
 * * `@end SomeComponent`: same as above, but only mark the end for the given component
 *   ```ts
 *   const SomeStory: ComponentStory<typeof Comp> = (args) => <Comp {...args} />;
 *   const OtherStory: ComponentStory<typeof Comp> = (args) => <Comp {...args} />;
 *   OtherStory.args = { prop: 1 };
 *   // story-code @end OtherStory
 *   ```
 * * `@include-default`: include the default code export. Can occur in an `@end` line
 *   or on the line following a natural or designated end.
 *   ```ts
 *   const SomeStory: ComponentStory<typeof Comp> = (args) => <Comp {...args} />;
 *   SomeStory.args = { prop: 1 };
 *   // story-code @end @include-default
 *   ```
 * * `@include-start`: include from the top of the file through to the default code export.
 *   Can occur in an `@end` line or on the line following a natural or designated end.
 *   ```ts
 *   const SomeStory: ComponentStory<typeof Comp> = (args) => <Comp {...args} />;
 *   // story-code @include-start
 *   ```
 * * `@skip`: Skip the current line
 *   ```ts
 *   const somethingToIgnore = 1; // story-code @skip
 *   ```
 * * `@skip-next`: Skip the next line
 *   ```ts
 *   // story-code @skip-next
 *   const somethingToIgnore = 1;
 *   ```
 * * `@skip-start` and `@skip-end`: Skip a block of text, e.g.
 *   ```ts
 *   // story-code @skip-start
 *   const hideThis = 1;
 *   const andThis = 2;
 *   // story-code @skip-end
 *   ```
 *   There's nothing enforcing that you have to have a @skip-end if you have a @skip-start
