## Status
DRAFT
FINAL
## Summary
This RFC proposes two things:
This RFC proposes three things:
1. The scalar types in Leo (integers, fields, etc.) can have static methods.
2. The scalar types in Leo (integers, fields, etc.) can have static constants.
3. Those values that have a scalar type can have methods directly on them.
3. Expressions of scalar type can have instance methods called on them.
## Motivation

The ABNF would look as follows:
