I think it would really good to have in D, especially since bool 
parameters are basically banned in favor a struct:

// banned
string toString(bool prettyPrint);
toString(false);

// preferred
string toString(PrettyPrint p);
toString(PrettyPrint.no);

// With named parameters
string toString(bool prettyPrint);
toString(prettyPrint: true);

If named parameters don't allow reordering it won't be a problem with 
overloading.

A simple implementation:
