Ok, sorry for my question. It seems it needs to satisfy 
RandomAccesIterator concept. The allocator_type and pointers might be 
defined as thin wrappers if the pointer is different than value_type*. 
This however only be needed for data() method. Am I right?

Btw, how is data() defined? I've found only an info that it should 
return value_type*. This of course won't work for a hybrid_vector. Or 
maby it should return pointer type (like in VS2012 btw)? But then what 
is the purpose of this method?
