Is it okey to have similar functions in different packages? In teal.data we have data_label (to add label attribute to data) and var_labels here.
What about shortening name from formatters_var_labels to varlabels?

[m7pr]

@gogonzo do you think we also need to include obj_label from formatters
https://github.com/insightsengineering/formatters/blob/ffa09bb46eb28a9e269847b918c14c719c5d28b5/R/generics.R#L261C1-L283C2 ? Looks like it's a wrapper around S3 and S4 at the same time, where for S4 it uses standardGeneric and for S3 it just calls attr(x, "label"). I think in teal packages we focus on S3, so rewriting obj_label(x) <- label to attr(x, "label") <- label should be enough

at https://github.com/insightsengineering/coredev-tasks/issues/447 we decided to move those functions to teal.data insightsengineering/teal.data#155
