That's not redefining the value of 3 and 6. That's redefining the value o
f 
Integer(3) and Integer(6).  The expression "2 + 3" will still return 5.

Note that in Fortran and FORTH at least, it's pretty trivial to make the 

literal 3 refer to the value 15.  (By "pretty trivial" I mean "you might 
do 
it by accident.")
