Comment (by vbraun):
`SR.var` does exactly what the `declare_var` does without the drawbacks of
an additional global, so as it stands I'm against the ticket description.
`SR.symbol` and `SR.var` should probably be aliases but aren't. I wasn't
even aware of `SR.symbol`, which is why I only fixed the comma parsing in
`SR.var` in #7496.
How about something like `R.<x> = SR()` to get symbolic generators?
