It's not a kludge, any more than unchecked conversion is. I suspect
that C++'s greatest need for const_cast comes from having to support
old C libraries which did not use const in their interfaces. You
have a function which takes a 'char *' rather than a 'char const *'
parameter, but the documentation of the function promises that it
leaves the contents unchanged. You have a 'char const *' that you
need to pass to this function. So you cast away const.
