 This table solidifies the intuition that an operation pertaining to some data
-structure causes the protoobject to autivivify to such an object:
+structure causes the protoobject to instantiate to the right type just in time:

 In addition to the above data structures autovivifying, C<++> and C<--> will
 cause an C<Int> to appear, C<~=> will create a C<Str> etc; but these are
