I think the point is to have an equivalent to C#'s 'nameof'.
It would be evaluated at compile time to a string, but with the
advantage that it's clear that it's a name and not some random string
that just happens to look like a name.
I'd like to draw attention to this as the first contribution to the
thread that has given a precise meaning to the initial idea. It tells us
both what it means and why you might want it (at least if the OP
agrees). It seems to be being overlooked.
As others have amply demonstrated (short of proof, I know) what is being
asked is not possible with the information available at run-time. You
can't reliable get from the "reference", which is actually an
expression, to the text of the expression.
The parallel with f-string = is helpful, for which compile-time support
is essential, of course.
