I think there's an -optNoChecks or something already? IMHO, it's would be nice to basically treat them as asserts; leave them on by default, then have a system-wide switch in case you want to disable them for production and gain some performance at the risk of crashes rather than failures in case of running into untested incorrect usage. (Optionally with an added -optForceChecks in case you write code that depends on an error being thrown for incorrectly passed types… though that shouldn't really happen) Cheers, Henry PS: Sadly, summer in Norway has seen the best weather in ages :D
