Pointer to template types?

Every template creates a new type, so you can't put them as they 
are in an array. There are various solutions, none nice. You can 
try with a wrapper that performs type erasure, or simpler you can 
make all the same type giving them the string at run-time. 
Another solution is use OOP, something like (untested and I am 
not sure):

abstract class APerson {}
class Person(string name) : APerson {}
