Select tests based on marker with arguments

See original GitHub issue

v5.3.4 on Python 3.7/macOS

In conftest.py:

def pytest_configure(config):
    config.addinivalue_line("markers", "year(arg): this marker takes arguments.")

In test_example.py:

import pytest

@pytest.mark.year(2015)
def test_a():
    assert 2 + 2 == 4

@pytest.mark.year(2020)
def test_b():
    assert 1 + 1 == 2

Cannot figure out how to run tests marked year 2015, the one obvious way gives a crash:

$ pytest -m "year(2015)"
