No, not in general. There are a few special cases, though.

The foreach loop can assign value and index simultaneously.

   foreach (int i, char c; a) {
     writefln("a[%d] = '%c'", i, c);
   }

Many things can be done in the library. For example, the variable 
swap from your link:

   swap(i,j);     // more: http://www.dpaste.dzfl.pl/582f7ae2

For returning multiple values from a function in D, you use 
std.typecons.tuple.

Could you give more context for your specific example? What are 
you trying to do?
