Show HN: GDSL – 800 line kernel: Lisp subset in 500, C subset in 1300

The author built GDSL, an 800-line compiler kernel that implements a Lisp subset in 500 lines and a C subset in 1300 lines, with only minor unfinished features rather than fundamental compromises. After 16 months of foundational work, the project challenges the assumption that compilers must be millions of lines, demonstrating that useful and robust compilers can be remarkably small.
