Okay. Usually there is a source string in English language which 
is subject to translation:

```d
    int n = 3;
    writefln (_("n is %d"), n);
```

The source string in this example is `n is %d`. Now for every 
target language one creates seperate .po-files [1]. These files 
essentially contain pairs of source/target strings:

```
msgid "n is %d"
msgstr "n ist %d"
```

These .po-Files are compiled into .mo-Files from which at runtime 
the strings read.

If now interpolation is in play

```d
    int n = 3;
    writefln (_(i"n is $(n)"));
```

How is the translation workflow organized now? What is put in the 
po-Files?
