The ternary operator is dissapointed.

C compilers tend to have an inlining extension, such as __inline/declspec stuff. Common Lisp implementations have inline/notinline declarations as well, however unlike the C ones, those are specified in the standard, however some Lispers(including me), believe that those 2 are themselves not enough as one might want to be able to control wether function calls are direct or indirect too, which is more important in Lisp as it allows redefinition at runtime (of just about anything you can think of).
