You'll probably want to convert id to a string there

import std.conv;

  "public immutable(int) getId() const { \n" ~ to!string(id) ~ ";

and also put in return for that function:
  "public immutable(int) getId() const { \n return " ~ 
to!string(id) ~ ";


and it should compile. What was happening before is string ~ int 
implicitly converts the int to a char, and cast(char)(3) isn't a 
printable character, and isn't allowed in D source code.

do you perhaps want to!string(id) ???

Me too but the following looks nice too:
