# Generalized iteration
|
|
|
|
## Summary
|
|
|
|
Introduce support for iterating over tables without using `pairs`/`ipairs` as well as a generic customization point for iteration via `__iter` metamethod.
|
|
|
|
## Motivation
|
|
|
|
Why are we doing this? What use cases does it support? What is the expected outcome?
|
|
|
|
## Design
|
|
|
|
This is the bulk of the proposal. Explain the design in enough detail for somebody familiar with the language to understand, and include examples of how the feature is used.
|
|
|
|
## Drawbacks
|
|
|
|
Why should we *not* do this?
|
|
|
|
## Alternatives
|
|
|
|
What other designs have been considered? What is the impact of not doing this?
