+** - too few arguments:   unrecoverable.
+** - wrong argument type:   recoverable, if coercion succeeds.
+** - bad argument value:  unrecoverable.
+** - stack overflow:        recoverable, if stack reallocation succeeds.
+** - extra handling:        recoverable.
+**
+** The unrecoverable cases throw an error with lj_err_arg(), lj_err_argtype(),

+** The recoverable cases return 0 or the number of results + 1.
+** The assembler VM retries the fast path only if 0 is returned.
+** This time the fallback must not be called again or it gets stuck in a loop.
