Yes they exist, that field is called "code-generation", "generative 
programming" etc.

I don't feel like describing all ideas - it's nothing really intersting 
anyway, just a learning project (to get to know language features), but 
obviously it's not for regular programming - I know text editors can do 
that just fine. Simply in some situation I think instead of generating 
data I'd better generate some code.
