* 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.
