Yes, I think there's a difference between having a graphical 
representation for code (see my other email on the custom web 
cells---I'd *love* to see graphical widgets that represent code) and 
manipulating and escaping a text string to be valid python code.


Hmmm...or am I contradicting myself?  Would it be better to send a JSON 
representation of the blockly cell to the kernel in a special message 
that means "here is a blockly description; make a Blockly object that 
has a .__call__ attribute and call it" and have the kernel generate the 
python code?

Thanks,

Jason
