Because lists are commonly used, they have shorthand type notations.
- The type <c>list(T)</c> has the shorthand <c>[T]</c>.
- The shorthand <c>[T,...]</c> stands for
- the set of non-empty proper lists whose elements are of type <c>T</c>.
+ The types <c>list(T)</c> and <c>nonempty_list(T)</c> have the shorthands
+ <c>[T]</c> and <c>[T,...]</c>, respectively.
The only difference between the two shorthands is that <c>[T]</c> may be an
empty list but <c>[T,...]</c> may not.

Also for convenience, we allow for record notation to be used.
Records are just shorthands for the corresponding tuples.
