- raises / warns with a string as the second argument
Deprecated since version 4.1.

- pytest_funcarg__ prefix
Removed in version 4.0.

- getfuncargvalue

- Metafunc.addcall
Removed in version 4.0.

Fixes: pytest-dev#209

-Why the ``pytest_funcarg__*`` name for funcarg factories?
----------------------------------------------------------------
-
-When experimenting with funcargs an explicit registration mechanism
-was considered.  But lacking a good use case for this indirection and
-flexibility we decided to go for `Convention over Configuration`_ and
-allow to directly specify the factory.  Besides removing the need
-for an indirection it allows to "grep" for ``pytest_funcarg__MYARG``
-and will safely find all factory functions for the ``MYARG`` function
-argument.  It helps to alleviate the de-coupling of function
-argument usage and creation.

 Can I yield multiple values from a factory function?
