Generator TSend, and foreach over a generator that requires send()phpdoc_advanced_generator_generic measures TValue;
generics_generator_get_return measures TReturn. This file measures
TSend: send() rejects the wrong type, and iterating a generator whose
send type is non-nullable is unsafe because foreach never sends.
