How do you update multiple columns using Slick Lifted Embedding?

With recent versions of Slick, this way of writing it works:

Users.filter(_.id === filterId)
     .map(x => (x.name, x.age))
     .update(("john", 99))

Be careful to remember the extra parentheses if you are updating more than one property otherwise you might get a compiler warning.

I figured it out. It should be like this

val map = Query(AbilitiesTable)
  .filter(_.id === ability_id)
  .map(ab => ab.verb ~ ab.context)

map.update(("", ""))

Typesafe, why your documentation is so bad ? I have to Google pretty much every silly thing or dig through unit-tests for hours. Please improve it. Thanks.
