Re: [Boost-users] boost::any with const value types

I'm finding that if I store a `char*` versus `char const*` in a boost::any object, that this impacts the behavior of boost::any_cast. I do not find this documented anywhere.

For example, if I store a const qualified character pointer in a boost::any object, then I do `boost::any_cast(......)`, it will throw. Changing the type to `char const*` fixes it.

Is this by design? I find this makes things more difficult to deal with since I don't always know if the type I'm getting is const or not. Also my implementation does not change depending on constness.

Yes, this is by design. The rule is that you can only get out the same type that you put in. char * is not the same type as char const *. In Christ, Steven Watanabe
