Sequel.

Sequel is a transformation of ideas that is composed of
the 'on'-field selector Trip followed by the specialized
search operation Suit.  The following figure illustrates
a typical situation in which Sequel is applied:

                              o-----o
         o--------------------|--o  |
         |  o---o  o---o  o---o  |  |
         o->| m |->| n |->| ) |--o  |
            o---o  o---o  o---o     |
            ^             ^         |
            |      o------|---------o
            |     /       |
trip (this) |    /        | sequel (this)
            |   /         @
            |  /
     o------|-/---------------------o
     |  o---o< o---o  o---o  o---o  |
     o->| ( |->| a |->| b |->| c |--o
        o---o  o---o  o---o  o---o
        ^
   this |
        @

function sequel (this: idea): idea;
begin
 sequel := suit (trip (this))
end;
