How about when  a function takes two parameters, one const and the other
non-const. If
the caller passes the same object (by reference or through a pointer)
for each parameter
should it be smart enough to know that the const object may have
actually changed through 
the other parameter ? Or is it the responsibility of the programmer
writing the calling code
(in which case I would never use const for functions taking two or more
parameters of the same type).

I'm learning C++ and have been staying away from const parameters
because I wasn't
sure how a compiler would handle the above case.

Are there any rules that cover this case ?
