--- Comment #4 from Benjamin Schulz <schulz.benjamin at googlemail dot com> ---
Also the Openmp specification for mapper says:

https://www.openmp.org/spec-html/5.2/openmpsu61.html

A structure type T has a predefined default mapper that is defined as if by a
declare mapper 


The question then is whether something like this:

template <typename T>
struct myvec
{
size_t len;
T *data;
};


Is called a structured type.

I would say yes, because only then one can use mapper with templates,e.g. in a
header for a library, where the template type T has not yet been specified
(which is then done by the users of the library)...
