-Type Rules
-==========
-
-A -> B means, Type A can be converted to type B implicitely.
-A -!> B means, Type A cannot be converted to type B implicitely.
-A_List is the type that contains a list of elements of type A
-
-Iff T1 -> T2, then T1_List -> T2_List.
-T -> T_List.
-T_List -!> T.
-
-Types always come in pairs: T and T_List.
-There are no lists of lists.
-
-A type can be in zero or one conversion group.
-Every type in this group can be converted to any other implicitely.
-The types within a group are ordered by their "rank".
-When two types with different rank are used in one expression,
-the type with lower rank is converted to the other.
