Why don't we fix the nuisance part without making it less attractive:
class _E(float):
def __pow__(self, other):
if self is e:
return exp(other)
else:
return pow(self, other)
e = _E(2.718281828...)

I would rather see
from math import π
work in the future Pythons.
I like Vi Hart, but I am firmly on the π side in the π vs. τ debate. The problem with τ is that it is visually smaller than π, actually twice smaller: π ≈ ττ, but the actual definition is the opposite.
