CLRHack: handler-bind and handler-case

In the CLRHack compiler, handler-bind is a primitive form used to register condition handlers in the dynamic environment. It operates by managing a thread-local list of active handler objects, ensuring that condition signaling follows the standard Common Lisp search and execution rules. Handling of handler-bind When the compiler processes a handler-bind form, it generates CIL code that performs the following steps: Capture Previous State: It calls Lisp.HandlerControl::GetActiveHandlers() to retrieve the current list of active handlers and stores it in a frame-local variable. Construct New List: For each binding, it evaluates the condition type and the handler function (which is typically a closure). It instantiates a new [LispBase]Lisp.Handler object and conses it onto the current handler list. Install New State: It calls Lisp.HandlerControl::SetActiveHandlers(new_list) to update the dynamic environment for the current thread. Protected Execution: The body of the handler-bind is…
