What do you guys think of introduce a new parameter in the vector template,=
=20
taking out the implementation of "grow" method from the it=C2=B4s guts and =
put=20
it on a separated class ?
=20
std::vector<int, std::allocator<int>, std::grow_ratio<1,2>>  g2;  //each=20
overflow, it doubles the size;

std::vector<int, std::allocator<int>, std::grow_fix<5>>          gf5;    //=
=20
each overflow grows 5 elements

std::vector<int, std::allocator<int>, std::grow_scaling< scale<0,10, 1>,=20
scale<11, 100, 2>, scale_greater< 100, grow_ratio<1,3> >>  gcomplex;
     grows one by one from 1 to 10, grows 2 by 2 from 11 to 100 and triples=
=20
it size when it became bigger than 100



using current size and the location of current data ( and probably more=20
information ), it can decide how much allocate

struct grow_algorithm {
   size_t new_size(const T* current_data, size_t current_size) {...}
};
