| ============== |
| |
| This check flags postfix ``operator++`` and ``operator--`` declarations |
| if the return type is not a const object. This also warns if the return type |
| is a reference type. |
| |
| This check corresponds to the CERT C++ Coding Standard recommendation |
| `DCL21-CPP. Overloaded postfix increment and decrement operators should return a const object |
| <https://www.securecoding.cert.org/confluence/display/cplusplus/DCL21-CPP.+Overloaded+postfix+increment+and+decrement+operators+should+return+a+const+object>`_. |
