Maybe year ago here was a discussion about autonomous transaction design - Robert proposed transaction scope - some like 'BEGIN AUTONOMOUS", I proposed function level. The syntax is not pretty important - this functionality is interesting - mainly for loging to tables - but there are risks - it again border transactional| untransactional - autonomous transactions are "untransactional" from outer transaction perspective - so some unwanted artefacts or risks are possible there - and application design should to respect it.
