Hello Aniket,

I cannot tell you which direction is the best for you. However, I recommend
a topic that you are really interested in and that you want to continue
even after GSOC.

Clang and GCC still do not officially support Ranges - so I would leave
that out (
Right now we should postpone the discussion of concepts for the tensor type.
