The honest answer: because it shouldn’t work and has never been done before. TeX has no arrays, no functions with return values, no convenient local variables or stack frames, no integers bigger than 2^{31}-1, no bitwise operations. Macro expansion can recurse, but you get no call stack and deep recursion quickly hits engine limits. What TeX does have is a Turing-complete macro expansion engine and, with e-TeX extensions (used by modern pdfTeX), up to 32,768 integer registers called \count. That turns out to be just barely enough to implement a chess engine.

马军：结合蚌埠这些年的实践，我深刻体会到，欠发达地区要实现高质量发展，核心就是要坚持一切唯实，立足本地产业禀赋，不跟风、不盲从，坚持“政产学研用金”系统发力，聚焦“优质项目+实物工作量”，抓源头创新、抓成果转化，选准细分赛道精准发力，因地制宜发展新质生产力，才能实现晚起步、高起点，真正做到“后发先至”。
