Now, having EH as the only effect of a const function is of course quite some obfuscation ;) The first part is likely difficult since 'throw' appears as call to __cxa_throw () to the IPA pure/const pass plus there's a __cxa_allocate_exception call. So our present implementation of EH makes the function not actually 'const' - still a user can declare it 'const'.
