Replying to [comment:8 vdelecroix]:
> The name `var` by itself makes a lot of confusion. There are Python
variables which are a very different concept. What about calling it
`symbol` or `Symbol` as it is done in [http://www.sympy.org/en/index.html
sympy]?
Definitely not `Symbol()`. As for `symbol()`, it could have been a better
name choice than `var()`, but I doubt switching to it now is a good idea.
The benefits are not that significant, and since `var()` is proabably one
of the most widely used functions outside the sage tree itself (in
particular, in random code snippets), the compatibility break would be a
pain for many of people (the recent deprecation of `pol.coeffs()` already
was pretty bad from this point of view).
