I've made a function for strings:

```D
string replaceTokens(in string tmpString, in string[string] aa) {
     import std.array : replace;

     string result = tmpString;

     foreach(key, value; aa) {
         string addBits(in string root) {
             return "{" ~ root ~ "}";
         }
         result = result.replace(addBits(key), value);
     }

     return result;
}
```
