Inconsistent rebinding rules for function arguments

From a C-programmers perspective, the choice of keyword const can be interpreted both correctly as char * const a; (binding cannot change) and incorrectly as const char * a; (value cannot be manipulated via the binding). So it may create some confusing. I have no better suggestion though…

Note that there already is a const keyword that can be used on global variables and already means that the binding cannot change.
