(This is not the first chicken-and-egg problem we've had. The setting needs booleans before perl 6 enums have been defined, so there's a BOOTEnum thing. At one point it started leaking out, and because it's not a proper perl 6 class but raw NQP it caused problems.) -- brandon s allbery kf8nh sine nomine associates allber...@gmail.com ballb...@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
