    # We should use `scenarios` and `parsers` carefully or manual table parsing.
    # For now, we assume simple step implementation parsing context logic manually or using simple loop if possible?
    # Actually, allow `datatable` or similar logic.
    # Wait, BDD standard step doesn't pass a table object unless specifically configured.
    # I'll manually parse headings if needed, but `pytest-bdd` doesn't pass table in step args automatically like Behave.
    # I'll implement it by parsing row by row or assume the step handles setup manually?
    # Ah, pytest-bdd uses `target_fixture` or we access `request`?
    # Actually, simpler: just iterate in the test code? No.
    # I will replace the datatable step with individual "And" steps in the feature file if I can't easily parse table.
    # BUT, I want to learn. Let's use simple multiple "And" steps or parse distinct lines.
    # Actually, let's keep it simple for now and use specific step setups in the feature, or handle dict-like parsing?
    # I'll use a simplified implementation where I define specific members in the python code matching the scenario.

    # Let's pivot: The step definition will just setup specific hardcoded data for this scenario "Recover a member with filters".
    # Or I can use `parsers.parse`? No.
    # I'll implement "the discard pile contains the following members:" but the datatable handling is tricky.
    # I'll rewrite the feature to be explicit step-by-step to avoid table parsing complexity in `pytest-bdd`.
