There already is a string method, which does the same thing that string() does
for the Array type that DataArray tries to mimic.
julia> da = @data([1, 2, 3])
3-element DataArray{Int64,1}:
1
2
3
julia> string(da)
"1\n2\n3\n”
In most cases, I’d advocate doing convert(Vector{UTF8String}, da), but that
method fails for Array, so it should also fail for DataArray unless we change
Base Julia.
