   I don't understand this issue... example of what behaviour is needed?

   This is the current behaviour:

   dict <- dictionary(list(country = c("united states", "mexico", "canada"), 
                           "law words" = c('law*', 'constitution'), 
                           freedom = c('free', "freedom", 'libertarian')))
   
   print(dict)
   print(dict[1]) # not a dictionary
   dictionary(dict[1]) # does not work

   but it should be

   print(dict[1:2])
   
   # Dictionary object with 5 key entries.
   # - country:
   #     - united states, mexico, canada
   # - law words:
   #     - law*, constitution
   
   dictionary(dict[1:2])
   
   # Dictionary object with 5 key entries.
   # - country:
   #     - united states, mexico, canada
   # - law words:
   #     - law*, constitution
