VerticalList -- a type of visible self-initializing list that prints vertically

Synopsis

Many operations on lists apply to vertical lists, since it is a VisibleList. The main difference is the way that it is displayed.

i1 : a .. e

o1 = (a, b, c, d, e)

o1 : Sequence

i2 : v = VerticalList oo

o2 = { a }
     { b }
     { c }
     { d }
     { e }

o2 : VerticalList

i3 : v_1

o3 = b

o3 : Symbol

i4 : length v

o4 = 5

It is easy to get a normal list back for those operations which do not apply to vertical lists:

i5 : toList v

o5 = {a, b, c, d, e}

o5 : List
