 /**
+ * This is meant to proxy the `...rest` parameter to a snippet function. Basically,
+ * this array will be full of functions that need to be invoked to unwrap their value.
+ * We have no way of forcing that invocation in all circumstances -- for example, if
+ * a user passes the rest array to a function that then accesses it via `rest[0]`, we
+ * would need to transform that into `rest[0]()`. That's effectively what this proxy does.
