the better soloution is dlopen/dlsym this allows the descision on what to
use to be moved to app development time or even runtime. (e.g. only using
new features if they are actually availible)

unfortunately doing this by hand is tedious++ so i think code generation
will have to be used to reasonablly do this. basically you have to generate
stubs that check if a procvar is nill,call a function to populate it if it
is nil and then call down the procvar. the code generator would take a name
and a parameter list and spit out theese stubs.
