Heather

Heather is the reference programming language shipped with H-hat. It is named after a plant¹ and a song².

The language is being developed to present all the concepts H-hat aims to accomplish: high-level abstraction language, rule system for strong compliance on quantum rules and quantum physics-respecting constraints, and to present a quantum software engineering side closer to the classical one.

It has some basic features, as well simple syntax; grammar strict structure and almost no ambiguity (if any) highlights Heather capabilities, promoting code that is easy to write, read, and reason about.
