This syntax is syntactically ambiguous.

struct StringNumber
{
     string s;
     string opBinary(string op)(string b)
     {
         import std.conv;
         return mixin(`(this.s.to!long ` ~
             op ~ ` b.to!long).to!string`);
     }
}

unittest
{
     assert(StringNumber("4")+"2" == "6");
     assert(StringNumber("4")-"2" == "2");
     assert(StringNumber("4")*"2" == "8");
     assert(StringNumber("4")/"2" == "2"); // Conflict!
             // Division by string, or nested comment?
}
