p_array about xtensor.jl

[SylvainCorlay]

Hum, this is weird. I don't reproduce here. Can you give more details about your setup (compiler version?)

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

It seems to be picking up an older version of the xtensor headers in your anaconda installation.

I should make things so that it only considers the Xtensor.jl directory where we vendor xtensor.

Reproduced and fixed!

Nice, thanks!
