The infinitely stacked world \(D^2 \times \mathbb{R}^2\) is the universal cover of Bobs world \(S^1 \times D^2\), as it is simply connected and covers Bobs world (see the definition of universal cover above).
One thing you’ll notice quickly, however, is the presence of obviously fake profiles. When I searched for singles near me, I encountered a surprising number of stunningly beautiful women in a small rural town near my city — all with airbrushed photos and vague, AI-sounding profile descriptions.

The language is pure, lazy, and has no loops. Every iteration is recursion, and recursion costs stack frames. Since Nix 2.20, the evaluator caps call depth at 10,000 (configurable via max-call-depth, but the default is what you'll hit). Before 2.20, the limit was whatever your OS allocated for the process stack: non-deterministic across machines, occasionally baffling to debug. Tail-call optimization would help. There's even a FIXME comment in ExprApp::eval() acknowledging it. But the evaluator's structure (a local variable that stays live across the recursive eval call) prevents the tail position from being optimized, and nobody has restructured the code. Tvix, the Rust-based evaluator, handles TCO in many cases. The reference C++ evaluator doesn't.
