““Any sufficiently complicated C or Fortran program contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of Common Lisp.””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Complex low-level code often recreates high-level language features inefficiently, leading to bugs and slow performance.
In simple terms: Low-level code can duplicate high-level features poorly.
