Here I have written "various situations" because I have given a 
list of those "various situations" in past posts.
I think the semantics is sufficiently natural, simple, and it's 
same for all those cases. I think the main problem in D is 
syntactic.

It also avoids the programmer to think about useless details, 
leaving more brain for more important things. Assigning the 
fields to variables like this:

const uselessTmp = foo();
immutable something = uselessTmp[0];
immutable secondThing = uselessTmp[1];
const theLast = uselessTmp[2];

is as efficient as leaving that to the compiler.
