Makes a string, mixes it into the source code and then compiles it.

Just pass the runtime values to the template:
import std.stdio;
void main(string[] args) {
if (args.length > 2) {
writeln(B(args[1], args[2]));
}
}
$ ./deneme abc xyz
string abc;
string xyz;
That is pretty amazing that the same function can be called at compile
time and runtime.
