readability-avoid-const-params-in-decls
=======================================
Checks whether a function declaration has parameters that are top level
``const``.
``const`` values in declarations do not affect the signature of a function, so
they should not be put there.
Examples:
.. code-block:: c++
void f(const string); // Bad: const is top level.
void f(const string&); // Good: const is not top level.
