 * This marks a field in a class with {@link Procedure} methods as part of the context the procedure is invoked in.
 * Practically, this means that before the procedure is called, fields with this annotation are automatically
 * populated with implementations of the specified APIs.
 *
 * In fact, apart from static fields, only fields with this annotation are allowed in classes that
 * define procedures. Each of the fields must be public and non-final.
