/// There are two options:
///
///   - `AssertMacros`: A comma-separated list of the names of assert macros to
///     be checked.
///   - `CheckFunctionCalls`: Whether to treat non-const member and non-member
///     functions as they produce side effects. Disabled by default because it
///     can increase the number of false positive warnings.
