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.
Some companies have experimented with an alternative approach: compressing schedules into four 10-hour days, but there are trade-offs. One study found that longer days on the clock can strain employee health and make it more difficult to manage caregiving responsibilities, according to an analysis by APA. While job satisfaction increased under this model, absenteeism and productivity are often unchanged.，更多细节参见易歪歪
