I am trying figure out if it is possible to use package name not explicitly as eg DataFrames etc or as a String variable with a name of this module with using. My test code is:

dependencies=["CSV", "DataFrames", "Plots"]
for pkg in dependencies
    if !haskey(installed_packages, pkg)
        Pkg.add(pkg)
    end
    print(pkg)

   using .pkg
    
end

It breaks on using .pkg (also tryid without a dot, with error
TypeError: in using, expected Symbol, got a value of type Core.SlotNumber
