Easy saving of Dict{Tuple,Number} to JSON?


I was wondering if there was an easy way to save a Dict{Tuple,Number} (see example below) to JSON.

d = Dict((1,:A) => 1, (1,:B) => 2, (2,:A) => 3, (2,:B) => 4)

I think JSON3 or LazyJSON might be what I’m looking for, but the documentation seems quite involved - I would just like someone to show me the 3 or 4 lines I have to write to save and load this type of Dict.
