The new API for creating a write concern (added in v1.12.0) makes defining write concerns like "w:majority, j:true" somewhat awkward. It requires users to set the Journal field, which is a *bool. Go does not have a syntax for bool pointer literals, so you have to write

writeConcern := writeconcern.Majority()
j := true
writeConcern.Journal = &j

or

writeConcern := &writeconcern.WriteConcern{
	W:       writeconcern.Majority().W,
	Journal: writeconcern.Journaled().Journal,
}

This is a feature request from https://github.com/mongodb/mongo-go-driver/pull/1331.

Definition of done:

• Improve the API for enabling journaling on write concerns.
