from context, it's recommended to use full specification like one
of the above.
+ stream
+ Also known as a "file-like object". An object which provides sequential
+ read-write access to the underlying data. A stream object implements
+ a corresponding interface, which consists of methods like ``read()``,
+ ``write()``, ``readinto()``, ``seek()``, ``flush()``, ``close()``, etc.
+ A stream is an important concept in MicroPython, many I/O objects
+ implement the stream interface, and thus can be used consistently and
+ interchangeably in different contexts. For more information on
+ streams in MicroPython, see `uio` module.
