There are number of commonly accepted concepts that are redefined  or reevaluated in Xreate. 

* Interface as subset. Interface is comprised of common subset of features supported by all concrete implementations.
    See [[concepts/containers]]

* Top-down annotations(like function, objects annotations) are exposed to and could be intospected by client code or caller.  Most usefull is exposing of caller annotations to a callee code or bottom-up annotations.
 
* Lazy/eager execution antagonism. 
  It's possible to determine which sites of using resource should treat it as lazy resource or eager otherwise. 
  See [[concepts/exploitation]] for details.

* Static/dynamic antagonism

* Rapid development and optimization antagonism
from Concepts/containers,  "Rapid development and optimization antagonism"
 
* High-level feast or famine

===Static/dynamic antagonism===

Abstractions - hide implementation details. 

Inclusive development.

===Polymorphism===
Either instantiations or indirect calls
