I’m trying to use `Dict` as values in another `Dict` so I wrote the below code, that failed as shown in the comments:

```julia
fruits = ["apple", "orange", "banana"]
#=
3-element Array{String,1}:
 "apple" 
 "orange"
 "banana"
=#
fruits_matrix = Dict(fruits .=> false)
#=
Dict{String,Bool} with 3 entries:
  "orange" => false
  "banana" => false
  "apple" => false
=#
available_fruits = Dict{String, Dict{String, Bool}}
#=
Dict{String,Dict{String,Bool}}
=#
available_fruits["home"] = fruits_matrix
#= Failed with error:
MethodError: no method matching setindex!(::Type{Dict{String,Dict{String,Bool}}}, ::Dict{String,Bool}, ::String)

Stacktrace:
 [1] top-level scope at In[108]:1
=#

push!(available_fruits, "home" => fruits_matrix)
#= Failed with error:
MethodError: no method matching push!(::Type{Dict{String,Dict{String,Bool}}}, ::Pair{String,Dict{String,Bool}})
Closest candidates are:
  push!(::Any, ::Any, !Matched::Any) at abstractarray.jl:2159
  push!(::Any, ::Any, !Matched::Any, !Matched::Any...) at abstractarray.jl:2160
  push!(!Matched::Array{Any,1}, ::Any) at array.jl:859
  ...

Stacktrace:

=#
```
