bump: patch type: fix A function named like a built-in a call always takes is refused. function words(st, k) compiled, and every call to it became the built-in words(n) - n zeroed ints, with a pointer for n - and LLVM refused the IR far from the cause. A top-level function whose name a call always takes as the compiler's own (words, keep, print, save, load, key, ...; the table is selfhost/check/check_builtins.ludic, held to emit_call by ludic-dev syntax --check) is now an error at its declaration, as run already was. Every other built-in (buffer, floats, double, ...) yields to a function the program declares, in the checker as it already did in codegen.
