Trie contradicts its documentation

[bvdmitri]

In the documentation you can read the following

"Note that the keys don't need to be Strings:"
with the following example

julia> t = Trie{Int,Char}();

julia> t[1:3] = 'a';

julia> t[[2,3,5]] = 'b';

julia> keys(t)
2-element Vector{Vector{Int64}}:
 [2, 3, 5]
 [1, 2, 3]

however on [864edb3b] DataStructures v0.18.22 I get

julia> t = Trie{Int,Char}();
ERROR: too many parameters for type Trie
Stacktrace:
 [1] top-level scope
   @ REPL[8]:1

There is also no built-in documentation for Trie

help?> Trie
search: Trie write RBTree Type stride

  No documentation found for public symbol.

  Summary
  ≡≡≡≡≡≡≡

  mutable struct Trie{T}

  Fields
  ≡≡≡≡≡≡

  value    :: T
  children :: Dict{Char, Trie{T}}
  is_key   :: Bool

and the children :: Dict{Char, Trie{T}} line suggest that keys indeed need to be Strings
