* Extractor function for a BindExpression type value node. | |
* A bind expression looks like `::this.foo` | |
* This will return `this.foo.bind(this)` as the value to indicate its existence, | |
* since we can not execute the function this.foo.bind(this) in a static environment. | |
* | |
* @param - value - AST Value object with type `BindExpression` | |
* @returns - The extracted value converted to correct type. | |
