when overloading broadcasted() one may sometimes want to call collect. However, this seems to not remember the size:
julia> a = reshape(1:100,(10,10))
10×10 reshape(::UnitRange{Int64}, 10, 10) with eltype Int64:
1 11 21 31 41 51 61 71 81 91
2 12 22 32 42 52 62 72 82 92
3 13 23 33 43 53 63 73 83 93
4 14 24 34 44 54 64 74 84 94
5 15 25 35 45 55 65 75 85 95
6 16 26 36 46 56 66 76 86 96
7 17 27 37 47 57 67 77 87 97
8 18 28 38 48 58 68 78 88 98
9 19 29 39 49 59 69 79 89 99
10 20 30 40 50 60 70 80 90 100
julia> b = Base.Broadcast.Broadcasted(+, (a, 100))
Base.Broadcast.Broadcasted(+, ([1 11 … 81 91; 2 12 … 82 92; … ; 9 19 … 89 99; 10 20 … 90 100], 100))
julia> size(b)
(10, 10)
julia> size(collect(b))
(100,)
Does one need to always use reshape(collect, size(b)) or is there a better way?
