The before and after measurements are done with the same dependency versions, and are after numba and sparse have already been imported - it seems that the compilation time is...

No - note the `18_nopython_backend` section, which is 0.1s longer. This is just for one of our compiled operator functions, and we have maybe around 5 of them? That was...

I'm wondering if actually we should just change the default to `copy=False`. I haven't yet found an internal call that would break if we did this.

Let's not merge this till we: * Decide on #282 * Re-profile it in isolation

See also #356

What does `Cl` stand for?

Can you give some examples of function names that might benefit from this? If we go that route, I'd be inclined to create a `clifford/unicode.py` file that just aliases existing...

Worth noting that things like `def ↑(x): ...` are not legal in python anyway

> caveats concern mostly "letter-like character" from UNICODE. This is indeed what I was alluding to in my comment above - the PEP you refer to is https://www.python.org/dev/peps/pep-3131/, thanks for...
