Consider the code: filter(n -> true, collect(1:0))
this returns a 0-element array. However if I don't collect the iterator
into an array:
filter(n -> true, 1:0)
I get the error
Error: TypeError: typeassert: expected AbstractArray{Bool, N}, got
Array{Int64, 1} in filter at array.jl:923
It seems like this should also return a 0-element array, since if the
iterator is non empty, e.g.
filter(n -> true, 1:2)
I get a two the element array [1,2].
