Why? It documents that the parameter is not modified in the
program,
Yes, but callers couldn't care less -- which is why C++ allows this:
void f(int i); // interface
void f(const int i) // implementation, locks down 'i'
{ ... }
and additionally makes the compiler tell you if you break the
promise nevertheless. If it was not your intention to modify the
parameter (even though it's just a local copy), the compiler error
can hint you at your mistake.
Yes, I use that a lot, if the function is messy enough.
It can be useful to know that 'i' still has the same value
two pages down in the code ...
function. :-)
