Aliasing can be detected at run time and appropriate code called. If the code is short enough that this produces an unacceptable overhead, then subroutine call time dominates anyway and the whole thing should have been inline and it becomes a compiler problem. (yes, I know this can lead to a combinatorial explosion... but I'm not convinced that a 2-way case isn't good enough.) -- Peter da Silva. `-_-' +1 713 274 5180. 'U` peter@ferranti.com
