i'd say "codify, and add warning". since i patched the warning into the 
compiler, i have no more problems with the current rules: compiler tells me 
about possible incompatibilities with C, and i can either add `()` to 
silent the warning, or explicitly cast to the type i want.

i think most other people will prefer to get warning instead of code 
breakage too. at least i hope so. ;-)
