Why is "delete" unsafe?

If you delete something but keep a reference to it, at some point 
down the line, the memory could be reused.

Then your old reference points to a different type of object and 
could treat it differently.


Just for example:

string code = something;

delete code;

// but oops code is still there and pointing at some memory...

int[] something = new int(10); // this might reuse the memory


eval(code); // now this evals a bunch of ints as if they were 
code which certainly isn't what you expected
