Sorry, I took so long to send this, but based on my experiments and research I think it should present no problems to have const formal parameters.
The real problem with const comes from trying to use it for local and global variables. In this case, const objects need to be passed to const formal parameters. On the other hand, both regular modifiable objects and const objects alike can be passed to const formal parameters without any casts - since const parameters do not constrain the callers, but instead constrain the body of the function with the const formal to not allow it to try to change it. If this isn't clear enough, I can probably augment this explanation in the next few days (upon request from the group). Thanx Barry.
