Description

Current behavour:

julia> x = Accumulator{Int, Int}()
Accumulator{Int64,Int64}()

julia> isempty(x)
true

julia> x[1]=0
0

julia> isempty(x)
false

Under the multiset interpretttion I think this should be true

Research direction

Start at the Accumulator implementation and its isempty entry point, then reproduce the Julia REPL example from the issue. Done means an accumulator containing only zero-count elements is treated as empty while an accumulator with positive counts is not.
