Now, you might aver

non-standard or not-a-real-function".

Then it's like

You already accept that the "natural/unit
equivalency function" has range with
_constant monotone strictly increasing_
has _constant_ differences, _constant_,
that as a cumulative function, for a
distribution, has that relating to
the naturals, as uniform.
And that they always add up to 1, ....
That most certainly is among the definitions
of a distribution, the probabilities even
range between 0 and 1.
So, even though you refuse that this is
a real function, because it's not, yet
it's also a distribution, which it is.
"Standardly as a limit of functions"
if you won't, like Dirac's unit impulse
function, never actually so esxcept its completion,
yet necessarily actually so in the derivations
that depend on it, like Fourier-style analysis,
"real analytical character", say.
Then also that it really is "a continuous
domain" and "a discrete distribution",
just keeps pointing out how special it is,
"the natural/unit equivalency function".
One of at least three set-theoretic accounted
models of continuous domains, and establishing
that there are non-Cartesian functions via
an anti-anti-diagonal-argument.
