This is useful as it can pinpoint exactly what is frozen, as in many cases when a FrozenError is raised, you cannot determine from the context which object is frozen that you expect not to be. I'm not sure that using name_err_receiver as the C function for FrozenError#receiver is acceptable, but it doesn't appear to cause problems. Users of the current rb_error_frozen C function will have to switch to using rb_error_frozen_object or the new rb_raise_frozen_error in order to set the receiver of the FrozenError. Patch to implement this feature is attached. ---Files-------------------------------- Add-FrozenError-receiver.patch (6.48 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
