An ideal expression is:
-

-
a function returning an ideal
-
a combination of ideal expressions by the arithmetic operations
+ or *

^ or ** )
Note that the computation of the product i*i involves
all products of generators of i while i^2 involves
only the different ones, and is therefore faster.
-
a type cast to ideal
