For that alone please use const when it is needed. Some moron I had to 
work with once wrote a wrapper for some printing functions and in the 
most significant  of his functions he had
void PrintText(char*){/...}
and there was no way for me to write:
PrintText("Hello World");
in my code, I had to use the ugly:
PrintText(const_cast<char*>("Hello World"));
because of someone else's ignorance.
