+ * ``DEFINE_FIELD`` creates templated, non-virtual read functions. This means if we 
+ * want to "redefine" a field in a child class by calling ``DEFINE_FIELD`` again, then
+ * the function will be "hidden" instead of "override". This is important to remember
+ * when casting a pointer to a base type, as in this case the implementation from the
+ * base type will be used since the function created by ``DEFINE_FIELD`` is not virtual.
