proposal: a new string litteral to embed variables in a string

[Timothee Cour]

btw, another argument is type safety: my proposal has type safety inherited
from typesafe variadic templates, whereas the "%s" way of doing things is
fragile:

import std.stdio;
void main(){
  writefln("%s%s%s\n",1,2);//crash at RT
  writefln("%s%s\n",1,2,3);//silently accepts even though 1 more argument
  writefln("%s%d\n",1,"foo");//crash at RT: wrong format specifier
}
