Can not load dictionary with key::String and value::Function

[KronosTheLate]

But I can write it without error, which is extra worrysome.

MWE:

julia> using BSON

julia> my_func(x) = x^2
my_func (generic function with 1 method)

julia> bson("test.bson", Dict([:my_func=>my_func])); BSON.load("test.bson")  # No issue with symbol
Dict{Symbol, Any} with 1 entry:
  :my_func => my_func

julia> bson("test.bson", Dict(["my_var"=>pi])); BSON.load("test.bson")  # No issue with string key, non-function value
Dict{String, Irrational{:π}} with 1 entry:
  "my_var" => π

julia> bson("test.bson", Dict(["my_func"=>my_func])); BSON.load("test.bson")  # But string key and funtion value? Error
ERROR: MethodError: no method matching typeof(my_func)()
