VariantN opBinary(string op,  T)(T rhs) if ((op ==  "+" ||  op ==  "-" ||  op ==  "*" ||  op ==  "/" ||  op ==  "^^" ||  op ==  "%")  &&
         is(typeof(opArithmetic!(T,  op)(rhs))))

Arithmetic between VariantN objects and numeric values. All arithmetic operations return a VariantN object typed depending on the types of both values involved. The conversion rules mimic D's built-in rules for arithmetic conversions.

VariantN opBinary(string op,  T)(T rhs) if ((op ==  "&" ||  op ==  "|" ||  op ==  "^" ||  op ==  ">>" ||  op ==  "<<" ||  op ==  ">>>")  &&
         is(typeof(opLogic!(T,  op)(rhs))))
