 * When adding a new class, disable copy/assignment/move until you have a proven need for these capabilities. If a need arises, enable copy/assignment/move selectively, and when doing so validate that the implementation of the class supports what is being enabled.
   * Use ORT_DISALLOW_COPY_ASSIGNMENT_AND_MOVE initially
   * See the other ORT_DISALLOW_* macros in https://github.com/microsoft/onnxruntime/blob/master/include/onnxruntime/core/common/common.h
+* Don't use else after return. see: [https://llvm.org/docs/CodingStandards.html#don-t-use-else-after-a-return](https://llvm.org/docs/CodingStandards.html#don-t-use-else-after-a-return)
+* Don't overuse std::shared\_ptr. Use std::shared\_ptr only if it's not clear when and where the object will be deallocated. See also: [https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Rf-shared_ptr](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Rf-shared_ptr)
+* Avoid using the 'long' type, which could be either 32 bits or 64 bits.
