Export enum

In order to deal with the case where you specify the value of each instances, you may use:

julia> module A
           macro exported_enum(T, syms...)
               return esc(quote
                   @enum($T, $(syms...))
                   export $T
                   for inst in Symbol.(instances($T))
                       eval($(Expr(:quote, :(export $(Expr(:$, :inst))))))
                   end
               end)
           end
           @exported_enum fruit apple=2 banana=3
       end
Main.A

julia> using Main.A

julia> fruit
