zero-size zero-length etl::array without compiler extension

[dhebbeker]

Have you considered implementing a zero-length etl::array as std::array supports it?

I am looking for a container which behaves like a C-style or std::array which has no data members (sizeof(...)==0) if the array has no elements. The compiler I use does not support the GCC extension of zero length arrays T array[0].

I think the existing etl::array could be modified (using template specialization amongst others) to support this.

If you would agree on this feature I could provide a pull request. I expect the changes to be mostly boilerplate code.

Yes, I would think that a simple specialisation should work.
Go ahead and do the pull request.

I halt my attempt before beginning any implementation. At least for the time being. I realized that even empty classes have sizeof(...) > 0 per language standard. It would be still possible to implement support for a zero-length array. But it would not satisfy my needs.
