d1_style_operators.dd

The deprecation period for D1-style operators has ended.

Starting with this release, any use of the deprecated D1 overload operators
will result in a compiler error.

The corrective action is to replace all operators with their D2 equivalent.

The following D1 operator overloads have been removed in favor of `opUnary`:
  * `opNeg` must be replaced with `opUnary(string op)() if (op == "-")`
  * `opCom` must be replaced with `opUnary(string op)() if (op == "~")`
  * `opPostInc`must be replaced with `opUnary(string op)() if (op == "++")`
  * `opPostDec`must be replaced with `opUnary(string op)() if (op == "--")`
  * `opStar`must be replaced with `opUnary(string op)() if (op == "*")`

The following D1 operator overloads have been removed in favor of `opBinary`:
  * `opAdd` must be replaced with `opBinary(string op)(...) if (op == "+")`
  * `opSub` must be replaced with `opBinary(string op)(...) if (op == "-")`
  * `opMul` must be replaced with `opBinary(string op)(...) if (op == "*")`
  * `opDiv` must be replaced with `opBinary(string op)(...) if (op == "/")`
  * `opMod` must be replaced with `opBinary(string op)(...) if (op == "%")`
  * `opAnd` must be replaced with `opBinary(string op)(...) if (op == "&")`
  * `opXor` must be replaced with `opBinary(string op)(...) if (op == "^")`
  * `opOr` must be replaced with `opBinary(string op)(...) if (op == "|")`
  * `opShl` must be replaced with `opBinary(string op)(...) if (op == "<<")`
  * `opShr` must be replaced with `opBinary(string op)(...) if (op == ">>")`
  * `opUShr` must be replaced with `opBinary(string op)(...) if (op == ">>>")`
  * `opCat` must be replaced with `opBinary(string op)(...) if (op == "~")`
  * `opIn` must be replaced with `opBinary(string op)(...) if (op == "in")`

The following D1 operator overloads have been removed in favor of `opBinaryRight`:
  * `opAdd_r` must be replaced with `opBinaryRight(string op)(...) if (op == "+")`
  * `opSub_r` must be replaced with `opBinaryRight(string op)(...) if (op == "-")`
  * `opMul_r` must be replaced with `opBinaryRight(string op)(...) if (op == "*")`
  * `opDiv_r` must be replaced with `opBinaryRight(string op)(...) if (op == "/")`
  * `opMod_r` must be replaced with `opBinaryRight(string op)(...) if (op == "%")`
  * `opAnd_r` must be replaced with `opBinaryRight(string op)(...) if (op == "&")`
  * `opXor_r` must be replaced with `opBinaryRight(string op)(...) if (op == "^")`
  * `opOr_r` must be replaced with `opBinaryRight(string op)(...) if (op == "|")`
  * `opShl_r` must be replaced with `opBinaryRight(string op)(...) if (op == "<<")`
  * `opShr_r` must be replaced with `opBinaryRight(string op)(...) if (op == ">>")`
  * `opUShr_r` must be replaced with `opBinaryRight(string op)(...) if (op == ">>>")`
  * `opCat_r` must be replaced with `opBinaryRight(string op)(...) if (op == "~")`
  * `opIn_r` must be replaced with `opBinaryRight(string op)(...) if (op == "in")`

Note: The `opBinaryRight` overload operator takes precedence over any `opBinary` operators.

The following D1 operator overloads have been removed in favor of `opOpAssign`:
  * `opAddAssign` must be replaced with `opOpAssign(string op)(...) if (op == "+")`
  * `opSubAssign` must be replaced with `opOpAssign(string op)(...) if (op == "-")`
  * `opMulAssign` must be replaced with `opOpAssign(string op)(...) if (op == "*")`
  * `opDivAssign` must be replaced with `opOpAssign(string op)(...) if (op == "/")`
  * `opModAssign` must be replaced with `opOpAssign(string op)(...) if (op == "%")`
  * `opAndAssign` must be replaced with `opOpAssign(string op)(...) if (op == "&")`
  * `opOrAssign` must be replaced with `opOpAssign(string op)(...) if (op == "|")`
  * `opXorAssign` must be replaced with `opOpAssign(string op)(...) if (op == "^")`
  * `opShlAssign` must be replaced with `opOpAssign(string op)(...) if (op == "<<")`
  * `opShrAssign` must be replaced with `opOpAssign(string op)(...) if (op == ">>")`
  * `opUShrAssign` must be replaced with `opOpAssign(string op)(...) if (op == ">>>")`
  * `opCatAssign` must be replaced with `opOpAssign(string op)(...) if (op == "~")`

The following D1 operator overloads have been removed in favor of `alias this`:
  * `opDot` must be replaced with `alias this`
