Adds a sealing and unsealing function to attach (or detach) seals onto a class via impersonator properties. Since these properties override, they do not accumulate wrappers. Calling seal multiple times will still accumulate multiple seal values inside the property. A sealed class cannot be instantiated and a subclass may not add class members that match any of the sealed names in its sealed parent. These functions are intended for use by TR's `sealing->/c` contract, but are parameterized over checking functions and could be used for other purposes. |
