Example: julia> A = fill(fill(0,2), 3) 3-element Vector{Vector{Int64}}: [0, 0] [0, 0] [0, 0] julia> A[1][2] = 5 5 julia> A 3-element Vector{Vector{Int64}}: [0, 5] [0, 5] [0, 5] The result is not what I would expect. Instead, I would have expected to get julia> A 3-element Vector{Vector{I…

Ah yeah this tripped me up at first as well. If you look at the help page for fill: help?> fill If x is an object reference, all elements will refer to the same object: julia> A = fill(zeros(2), 2); julia> A[1][1] = 42; # modifies both A[1][1] and A[2][1] julia> A 2-element Vector{V…
