.. title:: clang-tidy - readability-const-return-type
Checks for functions with a ``const``-qualified return type and recommends
removal of the ``const`` keyword. Such use of `const` is usually superfluous,
and can prevent valuable compiler optimizations. Does not (yet) fix trailing
return types.
.. code-block:: c++
const int foo();
const Clazz foo();
Clazz *const foo();
Note that this applies strictly to top-level qualification, which excludes
pointers or references to const values. For example, these are fine:
.. code-block:: c++
const int* foo();
const int& foo();
const Clazz* foo();
