Description

$<, [[<, and (probably) [<- methods. We have the extracting versions implemented but not the updating ones, and that would be useful.

Motivating use case: schema detection for a dataset misreads a column, so take the autodetected schema, modify one field, and then re-create the dataset with the correct schema.
