The idea of the original post was a bit more complex: how can we invent new/better ways to express semantics in D code that will not forbid future D compilers to perform a bit of changes in the layout of data structures to increase code performance? Complex transforms of the data layout seem too much complex for even a good compiler, but maybe simpler ones will be possible. And I think to do this the D code needs some more semantics. I was suggesting an annotation that forbids inbound pointers, that allows the compiler to move data around a little, but this is just a start. Bye, bearophile
