Description
For example, select all Float64 columns.
One option might be df |> @select(<:Float64)... We should also take a look how this is done in dplyr.

Research direction
Start by tracing the @select entry point and its column-selection behavior in Query.jl. Compare the proposed eltype-based selection with the corresponding dplyr behavior. Done means users can select all columns matching a requested type, including the Float64 example, with coverage for that behavior.
