String interpolation

[tired_eyes via Digitalmars-d-learn]

Hi,
The only example of string interpolation I've found so far is on 
Rosetta Code:

void main() {
     import std.stdio, std.string;

     "Mary had a %s lamb.".format("little").writeln;
     "Mary had a %2$s %1$s lamb.".format("little", 
"white").writeln;
}

Is this a "proper" way of string interpolation in D? This looks a 
little clumsy. Are there any better approaches? Quick skimming 
through the docs didn't give anything.
