currently not all callbacks do proper checks for all arguments or even 
return values; some might even change esp when a wider context might be 
handy while dealing with such a list so don't rely too much on the 
interfaces to be kept the same in that respect (although the general 
idea will not change) (ps. some variants might show up eventually)

i'm sure taco will have a look at you hpack patch -)
