Comment (by mmezzarobba):

 Replying to [comment:3 nbruin]:
 > I suspect that Zimmerman's calculus book uses this stuff quite
 extensively, so deprecating/changing the current behaviour will likely
 lead to pushback from him, and probably rightly so.

 I'm not sure about `function()` and have little time to check now, but
 regarding `var()`, I think we tried to always use `x = SR.var('x')`.

 And IMO, the version of `var` that injects a variable in the global
 namespace should simply be deprecated, or possibly moved to
 `sage.ext.inteactive_constructors_c` if someone really care about it.
