I think the issue is that your opBinary requires that isNumeric!T be 
true.  This is the case if FixedDecimal is allowed to decay to the 
underlying int which is why it works when you use the alias this.  I 
recommend removing the alias this and adding another overload like this:

FixedDecimal opBinary(string s, T : FixedDecimal)(const T rhs)
