Rewriting map over Dict in julia 1.0

New to Julia
1

could I ask for help to translate this julia 0.6 statement to 1.0?

julia> mydict= Dict("One" => 1, "Two" => 2, "Three" => 3);

julia> map( x->(string(x[1], "S") => fill('*', x[2])), mydict)
Dict{String,Array{Char,1}} with 3 entries:
  "TwoS"   => ['*', '*']
  "OneS"   => ['*']
  "ThreeS" => ['*', '*', '*']

string(x[1],"S") creates the left side of the pair, the fill creates the right side of the pair, and I want to iterate over every item in the dict.

figured it out:

julia> Dict( string(key,"S") => fill("*", value) for (key, value) in mydict)
Dict{String,Array{String,1}} with 3 entries:
  "OneS"   => ["*"]
  "ThreeS" => ["*", "*", "*"]
  "TwoS"   => ["*", "*"]

You could also map over pairs(dict).

is this so? pairs(mydict) does not seem to do anything

julia> mydict
Dict{String,Int64} with 3 entries:
  "One"   => 1
  "Two"   => 2
  "Three" => 3

julia> pairs(mydict)
Dict{String,Int64} with 3 entries:
  "One"   => 1
  "Two"   => 2
  "Three" => 3

Using collect(dict) seems to do the trick.
