Return the boolean from evaluating the given marker against the environment. environment is an optional argument to override all or part of the determined environment. The *context* parameter specifies what context the markers are being evaluated for, which influences what markers are considered valid. Acceptable values are "metadata" (for core metadata; default), "lock_file", and "requirement" (i.e. all other situations).
