Well, second attempt. :-)
I need datatype witch can store some unknown amount of elements.
Elements must be referensed by index. Time for referencing is
critical parameter.
In C i can use array of pointers for that purpose, start from
some size and realloc() it on need. In scheme vectors are
applicable for that with one small exception -- they can`t change
size.
