I recently tried to implement a ranking algorithm, AllegSkill, to Python 3.

Here's what the maths looks like:

_{No, really.}

This is then what I wrote:

t = (µw-µl)/c  # those are used in
e = ε/c        # multiple places.
σw_new = (σw**2 * (1 - (σw**2)/(c**2)*Wwin(t, e)) + γ**2)**.5

I actually thought it is unfortunate of Python 3 to not accept √ or ² as variable names.

>>> √ = lambda x: x**.5
  File "<stdin>", line 1
    √ = lambda x: x**.5
      ^
SyntaxError: invalid character in identifier

Am I out of my mind? Should I have resorted for a ASCII only version? Why? Wouldn't an ASCII only version of the above be harder to validate for equivalence with the formulas?

_{Mind you, I understand some Unicode glyphs look very much like each other and some like ▄ (or is that ▗▖ ) or ╦ just can't make any sense in written code. However, this is hardly the case for Maths or arrow glyphs.}

Per request, the ASCII only version would be something along the lines of:

winner_sigma_new = ( winner_sigma ** 2 *
                    ( 1 -
                     ( winner_sigma ** 2 -
                       general_uncertainty ** 2
                     ) * Wwin(t,e)
                    ) + dynamics ** 2
                   )**.5

...per each step of the algorithm.
