OK, let's think about proposed SIN/sin approach once again. 
I see too much troubles with it: 
distinguish between system and user space function - trouble,
the same for variables - more troubles an. 
Making Maxima CS for user space imposes some "discipline"
on user - it inevitable forces him to be careful about case.
I don't see any trouble in expending this discipline
on system space as well.
