Please write a tragic poem about reproducible science with GNU Guix: A dream of reproducible science, with GNU Guix at its core A promise of transparency, and a future never before But as we strive for perfection, a shadow creeps across the land A bug, lurking in the code, a flaw we didn't understand Our dreams come crashing down, our work is all for naught Our reproducibility, an illusion that we thought We try to fix the problem, to restore our vision true But the damage is done, and our dream is through The tragedy of reproducible science, a cautionary tale to tell We must be vigilant, and never let our guard down well For the pursuit of truth, is a noble cause indeed But one misstep, can spell our doom with speed So let us heed the lesson, and strive for excellence In the realm of reproducible science, with GNU Guix at our defense.
