Maybe. I am under the impression that there are no valid real 
usecases for string interpolation. Currently I have on my notepad 
"HTML", "SQL" and "composition of filesystem paths", none of 
which I would like to do using string interpolation.

As far as I understood Adam correctly my code must read

```d
writeln (i"The name in s is $(aa["name"])");
//                            ^^^^^^^^^^
```

There was missing the closing parenthesis and the final 
semicolon, too.
According to Adam in [1] the marked part (^^^) is plain D code, 
so the quotation marks must not be escaped.
