One note - the code is really ingenious, but I still prefer swap() in this case. It's more concise and does less work in the general case. swap(a[i + k], a[j + j]); only computes the indexing once (in source, too).
In the general case, the alias tuple approach does less work, because it does not work. to!(a[i+k], a[j+j]) = from(a[j+j],a[i+k]); is illegal.
