Of course, if we went down that route, we would also need a
separate gamma for the Euler-Masheroni constant 0.577215664.. and who
knows how many other magical numbers the mathematicians come up with.

And getting physical constants in, like Planck's constant, was
just the result of them having special forms encoded as characters
in XCCS, not because we liked those particular ones and didn't like the
Gravitational constant G, Avogadro's constant L, the Boltzmann
constant k, the Rydberg constant R, the speed of light c, or any number
of others.

Besides, do we really want a character encoding to get involved in
determining whether "e" represents the mass of an electron, the
charge of an electron, or Euler's constant?
