WrapperType -- a class of lists with abbreviated constructors

Description

These are the types X of lists that can be constructed by expressions of the form X {a,b,c,...}, or, for lists of length one, by an expression of the form X a. They also act on sequences. 

i1 : X = new WrapperType of BasicList

o1 = X

o1 : WrapperType
 
i2 : X {a,b,c}

o2 = X{a, b, c}

o2 : X
 
i3 : X a

o3 = X{a}

o3 : X
