Alternatively, you can set up [`babel-plugin-macros`](https://github.com/kentcdodds/babel-plugin-macros) and

import `reghex` from `"reghex/macro"` instead.

This step is **optional**. `reghex` can also generate its optimised JS code during runtime only!

This will only incur a tiny parsing cost on initialisation, but due to the JIT of modern

Since the `reghex` runtime is rather small, for larger grammars it may even make sense not

to precompile the matchers at all. For this case you may pass the `{ "codegen": false }`

option to the Babel plugin, which will minify the `reghex` matcher templates without
