Simple example: a = [5.4,2.7,8] b = [5.3,2.1,"Jump"] typeof(a) # Vector{Float64} typeof(b) # Vector{Any} just as expected. Now try using map function: map(typeof,[a,b]) produces this: 2-element Vector{DataType}: Vector{Any} (alias for Array{Any, 1}) Vector{Any} (alias for Array{Any, 1})

Weird behavior with "map" function

What you’re missing is [a,b] promotes.
