I'm not sure if it is worth, but when I work with polynomial domains, I
am always looking for a

  variable: () -> %

function. This could be NNI -> % for multivariate domains. Another name
could be "generator", but I would be against it, because it is a keyword
in Aldor.

On the other hand, looking through the list of available functions, it's
pretty easy to come to the conclusion that one has to us monomial(1,1)
for a variable and if you have realised,

(1) -> f: SUP(INT) := x^3+2*x^2+x

         3     2
   (1)  ?  + 2?  + ?
                                    Type:
SparseUnivariatePolynomial(Integer)

also works just fine in the interpreter. This restricts the usefulness
of an "abbreviation" function to "programming in SPAD".
