Description
Related to user's problem report https://discourse.julialang.org/t/help-with-appending-row-in-read-in-dataframe-weird-behavior/87734.
When you write:
julia> df2 = CSV.read("test.csv", DataFrame, types=Any)
ERROR: ArgumentError: Non-concrete types passed in `types` keyword argument, please provide concrete types for columns: Any
you get an error. What can the user do to allow a flexible eltype for column read-in, like Any or e.g. Real?
