Is it possible to use templates to implement something like the `@show` macro from the Julia programming langauge in D?

```d
         assert(echo2("T $i, b, ${i-2}") == "writefln(\"T \", i, 
\", b, \", (i-2));\n");
```

It looks clean and understandable. What is not understandable is 
that it has not been included in std.stdio for over 10 years. I 
know, string interpolation has just been integrated, but why 
hasn't something like this been developed in 10 years that would 
have no side effects and would attract the attention of beginners?
