How else would you even use extras?
Oh, I suppose I could :slurpy any extra parameters into a dummy array. But that probably involves creating a dummy empty array on every call to the parrot sub. At any rate, I found and fixed the two PGE subs that weren't declaring their (unused) parameters. All p6rules tests now appear to pass in r10278 with .PARROT_ERRORS_PARAM_COUNT_FLAG enabled. Pm
