+Status
+""""""
+
+Last status was back in October. At that time I could
+
+::
+
+    def concept hello name as "hello" + name
+    1 + 1
+    sheerka.test()
+
+1. I can evaluate concepts
+
+::
+
+    def concept hello a where a
+    hello kodjo
+
+2. I have worked on BNF definition of the concept
+
+::
+
+    def concept twenties from bnf 'twenty' (one | two | three)=unit as 20 + unit
+    twenty one
+    eval twenty one
+
+3. I can mix complex concepts (concepts with more than one word) and Python
+
+::
+
+    twenty one + twenty two
+    twenty one + one does not work :-(
+
+
+4. I have a basic implementation for logging. With control of the verbosity
+
+5. The result of an user input evaluation is now persisted, alongside with the event
+that was used for it.
