*this

[Paul D. Anderson]

Looking at Don Clugston's BigInt code I see usage of "*this":

BigInt opMulAssign(T: BigInt)(T y) {
       *this = mulInternal(*this, y);
         return *this;
     }

I think I know what it does (passes this by reference) but I can't find any documentation that explains the usage. Can anyone point me to a source??
