(Sorry, name 'chicken-primitive-inlines.scm' was wrong, corrected.)

Yes, don't ;-)

These are dangerous routines, making assumptions about the types of  
their arguments. While not yet in service of Chicken 4 they are  
phasing in for Chicken 3. The purpose is to increase the readability  
of core code (and high-performance extensions, such as the 'mailbox'.)  
Also, the identifiers are not quite fixed.

Examples:

(include "chicken-primitive-object-inlines")

  (##sys#setslot v i '(a b)) -> (%vector-set! v i '(a b))
  (##sys#setislot v i 4) -> (%vector-set-immediate! v i 4)

  (##sys#slot l 1) -> (%cdr l)
  (##sys#setslot l 1 x)  -> (%set-cdr l x)

(include "chicken-thread-object-inlines.scm")

  (##sys#slot t 7) -> (%thread-reason t)
