would it be possible to have some kind of eponymous mixin
templates in the language?
I'd imagine it to look something like this:
````
import std.stdio;
mixin template interp(string S) {
mixin interp = S; //some fancy code to replace ${_var_} with
content of _var_
}
void main() {
int a = 5;
string b = interp!"hello ${a} world";
}
```
