Examples

  • I'd really like to be swimming in a nice cool pool right now.
  • You must be joking!
  • I happened to be waiting for the bus when the accident happened.
The perfect continuous infinitive:
to have been + present participle

Examples

  • to have been waiting
  • to have been painting

  • He pretended to have been painting all day.
