+ * generic/tclOOBasic.c (TclOO_Object_Destroy): Rewrote to be NRE-aware
+ when calling destructors. Note that there is no guarantee that
+ destructors will always be called in an NRE context; that's a feature
+ of the 'destroy' method only.
+
* generic/tclEncoding.c: Add 'const' to many function-internal vars
that are never pointing to things that are written to.
