# Summary
[summary]: #summary

One para explanation of the feature.

# Motivation
[motivation]: #motivation

Why are we doing this? What use cases does it support? What is the expected outcome?

# Detailed design
[design]: #detailed-design

This is the bulk of the RFC. Explain the design in enough detail for somebody familiar
with the project to understand, and for somebody familiar with the relevant component(s) to implement.
This should get into specifics and corner-cases, and include examples of how the feature is used.

# Drawbacks
[drawbacks]: #drawbacks

Why should we *not* do this?

# Alternatives

What other designs have been considered? What is the impact of not doing this?

# Unresolved questions

What parts of the design are still TBD?
