 In the 6.d language, the default default is the type object without the smiley
 constraint:

 A closing remark on terminology: this section is about the use of the type
 smileys C<:D> and C<:U> to constrain the definiteness of arguments.

 This is similar to placing type constraints on variables like C<my Type $var =
