+Why invent new language?
+------------------------
+
+* Grown as side effect of the pypy project
+
+* Python is too slow
+
+* Pyrex/C are ugly
+
+* We want to play with Python as much as possible
+
+What is RPython?
+----------------
+
+* Python (every RPython program has the same meaning
+  when run on top of CPython)
+
+* Restricted subset
+
+* Constructed from living objects - initialization
+  is fully done in Python
+
+* XXX more?
+
+Restricted, what do you mean?
+-----------------------------
+
+* No dynamic stuff (from __ methods only
+  __init__ and __del__ works)
+
+* No frames and such stuff
 
-* RPython - translation toolchain architecture overview
+* Full type inference - you cannot mix types
 
-* Example of metaprogramming, graph viewer etc.
+XXX crappy examples expand or delete (probably would be
+XXX better to just say few words
+
+* [1, 2, 3, 4] is ok, ['sss', 2] not
+
+* (1, 'xx') is ok, but cannot be mixed with ('xx', 1)
+
+Example of use case
+-------------------
+
+XXX write down some simple example for that one
+
+* Write code
+
+* test it
+
+* compile it
+
+* graph viewer
