Are you interested in detailed source code transformations after a 
specific analysis on a control flow graph?
Do you see use cases to drill down from higher abstraction levels to the 
abstract syntax tree to generate some adjustments?

How do you think about consequences and challenges like they are 
demonstrated by the semantic patch language from the software "Coccinelle"?
