The macro takes a single Rust identifier (`ident`) as argument and expands to a `{}` block (hence the double braces). The block defines a new wrapper function that calls the function `$name` and passes a pointer to the exception stack frame. Note that we're fixing the argument type to `*const ExceptionStackFrame`. If we used a `_` like before, the passed function could accept an arbitrary argument, which would lead to ugly bugs at runtime.
