not entirely sure why this works, but it fixes the issue #166

julia> using Tidier

julia> db = connect(duckdb());

julia> df1 = DataFrame(a = ["a", "b"], b = 1:2); df1db = dt(db, df1, "df1");

julia> df2 = DataFrame(a = ["a", "c"], c = 3:4); df2db = dt(db, df2, "df2");

julia> @chain df1db begin 
           @left_join(df2db, a = a)

This should be fixed now in the latest release so will close. It was a bug with the way that @chain was being exported.
