I also have a module that implements a tied hash purely in XS, but I don't see any problems with 5.8.2. The only changes between major perl releases I can find are between 5.005_03 and 5.6.0 (which changed the order of calls to FETCH/STORE when doing 'values %hash') and between 5.8.0 and 5.8.1 (which made DESTROY being correctly called in void context). I can see no change (from the API point of view) that affects how CLEAR is being called. If you'd like to have a look, my module (Tie::Hash::Indexed) can be built with debugging support by saying perl Makefile.PL enable-debug which allows you to trace each method call by exporting THI_DEBUG_OPT=d in your environment.
