We impose this limitation implicitly with the with* operations.  With this suggestion we'll need to check that 'lane' is a constant or alternatively allow non-constant 'lane' values, which would complicate the code generation.  Another concern is the duality of lane indicators, using both x/y/z/w and integers.  I much prefer the letters, because use of integers tends to cause big/little endian portability issues."}}
