 ### Snippets With Variants Improved
 
+This script would take those ideas a bit further and has 2 formats for snippets with variants
+
+* the old 1-indexed list of strings
+
+* a callable which will be fed with the choice `n`, if not provided the default value will be 1
+
+```python
+{
+    "attribute assign":
+        lambda n: "".join(["auto& $"+x+" = $1.$"+x+";\n" for x in string_range(2,n + 2)]),
+
+    "error line":lambda n:"std::cerr<< " + ' << " " << '.join(["$" + str(x) for x in range(1,n + 1)]) + " << std::endl;",
+    "error named":lambda n:"std::cerr<< " + ' << " " << '.join(['"${0}" << " " << ${0}'.format(x) for x in range(1,n + 1)]) + " << std::endl;",
+
