To be translated to or from a YAML sequence for your type T you must specialize
llvm::yaml::SequenceTraits on T and implement two methods:
-“size_t size(IO &io, T&)” and “T::value_type& element(IO &io, T&, size_t indx)”.
-For example:
+``size_t size(IO &io, T&)`` and
+``T::value_type& element(IO &io, T&, size_t indx)``. For example:
.. code-block:: c++
