Description:
 def deprecated(func, solution):
 """ Mark a parser or combiner as deprecated, and give a message of how to fix this. This will emit a warning in the logs when the function is used. When combined with modifications to conftest, this causes deprecations to become fatal errors when testing, so they get fixed. Arguments: func (function):
 the function or method being deprecated. solution (str):
 a string describing the replacement class, method or function that replaces the thing being deprecated. For example, "use the `fnord()` function" or "use the `search()` method with the parameter `name='(value)'`". """
