[julia-users] what is the easiest way to convert array type?

[cnbiz850]

I have an Array{Any,1}, but I want to convert to Array{String,1}. The 
only way I know is through comprehension.

julia> dt
3-element Array{Any,1}:
 "2010/1/4T15:00:00"
 "2010/1/5T15:00:00"
 "2010/1/6T15:00:00"

julia> dts = [convert(String, dt[i]) for i=1:length(dt)]
3-element Array{String,1}:
 "2010/1/4T15:00:00"
 "2010/1/5T15:00:00"
 "2010/1/6T15:00:00"
