This is so nineties, seriously :)

C is not a difficult language at all, and it doesn't have to be. A well 
written well structured library should give the programmer assertions 
that the code is still sane, and when you are on a critical performance 
path, you should be able to make the assertions disappear using a #define.

Performance means nothing whatsoever if the code is unreliable, and if 
your code doesn't help my code be reliable, a point is reached when the 
library collapses under it's own weight:

man assert
