It does indeed. Thanks for your

vector::operator[](size_type) in bits/stl_vector.h is currently implemented as
reference
operator[](size_type __n)
{ return *(begin() + __n); }
const_reference
operator[](size_type __n) const
{ return *(begin() + __n); }
A faster implementation would be:
vector::size() in bits/stl_vector.h is currently implemented as
size_type
size() const
{ return size_type(end() - begin()); }
A faster implementation is
size_type
size() const
{ return _M_impl._M_finish - _M_impl._M_start; }
Which avoids the temporary iterato
