there is a way of using a void* dtor* variant type and have type checks.

Err, what I meant to say was, this is no complete solution. I was merely showing a way of storing any type of object in one class. My actual propety object I made had full type checks, copy constructors and anythnig else I needed.

You'll never learn anything if you don't try it yourself anyway.

Given the small fact that your code will cause an access violation/seg fault in the constructor in the exact same way that code you've posted in another thread causes an access violation/seg fault in the constructor, it's very hard to believe that you've actually tested this code. If you want accurate comments about your code, you'll need to post your actual code.

In such cases you can usually just pass a string object by constant reference. Ta-da! No copy.

(Also, some implementations of std::string are able to avoid unnecessary copies/allocations under certain circumstances, but as this behavior is implementation-dependent it shouldn't really be counted on.)
