Construction and destruction?

I propose to do it like in a boost.lambda. Additionally adding `aggregate` and `new_aggregated_ptr`:
```
constructor()(arg_list) T(arg_list)
aggregate()(arg_list) T{arg_list}
destructor()(a) a.~A(), where a is of type A
destructor()(pa) pa->~A(), where pa is of type A*
new_ptr()(arg_list) new T(arg_list)
new_aggregated_ptr()(arg_list) new T{arg_list}
new_array()(sz, val_list) new T[sz]{val_list}
delete_ptr()(p) delete p
delete_array()(p) delete[] p
```
