Some additional topics. No content here but happy to discuss if there’s time:

• Meta programming with {targets}.
  • You can create ‘target factories’: targets that generate more than one target in your plan.
  • These are away to build domain specific abstractions into our plans
  • See: wlandau.github.io/targetopia/contributing.html
• For large projects {targets} supports having muliple plans.
  • I use this a fair bit, and it works well for projects that have separate phases.
  • E.g. maybe there’s a phase where you’re building a model, and then there’s a later phase after it’s been ‘in production’ where you analayse the performance. These could be separate plans in the one project.
  • Be careful about using it to break up a pipeline such that you revert to the classic ‘script per pipeline stage’ form.
