> By making `var` not a function you're also blocking off reasonable
programmatic use.
Exactly, and that is IMHO a big plus of the proposal.
Even right row you are not **supposed** to use `var` in library code, but
there is nothing stopping you. Programmatically generated symbolic
variables should always be declared as `x = SR.var('x')`. This is already
spelled out in the current `var` docstring.
