+YB. I am very worried about this proposal. It looks again like we would be
+creating another language to replace one we already have, namely python,
+mainly so that we could have introspection and programmable changes
+into an existing control flow structure (e.g. the standard DBN code).
+
+I feel that the negatives outweigh the advantages.
+
+Please correct me:
+
+Disadvantages:
+
+* much more difficult to read
+* much more difficult to debug
+
+Advantages:
+
+* easier to serialize (can't we serialize an ordinary Python class created by a normal user?)
+* possible but not easier to programmatically modify existing learning algorithms 
+  (why not the usual constructor parameters and hooks, 
+   when possible, and just create another code for a new DBN variant when it can't fit?)
+* am I missing something?
+
+I am not convinced that any of the stated advantages can't be achieved in more traditional ways.
