Impossible in the current version, unless you accept having a bunch of
dummy fields. It is not hard to implement:

template defineStaticImpl( T, int value, string name ) {
     // Do as below, no recursion.
}

template defineStaticImpl( T, int value, string name, string next, args...  
) {
     // Mostly as before.
}


template defineStaticImpl( T, int value, string name, int actualValue,  
args... ) {
     mixin defineStaticImpl!( T, actualValue, name, args );
}

My pleasure. Was a fun challenge.
