This works fine:
julia> x = 1:5
1:5
julia> y = [z^2 for z in x]
5-element Array{Any,1}:
1
4
9
16
25
and I can use similar solution with a simplified form:
julia> y = [x*2]
5-element Array{Int64,1}:
2
4
6
8
10
so I got brave and tried this, but it failed:
julia> x = 1:5
1:5
julia> y = [x^2]
ERROR: `*` has no method matching *(::UnitRange{Int64}, ::UnitRange{Int64})
in power_by_squaring at intfuncs.jl:56

or:
julia> y = [x*x]
ERROR: `*` has no method matching *(::StepRange{Int64,Int64}, ::StepRange{
Int64,Int64})
