how and in what aspects specifically (examples of pretty output that can't
be re-parsed ? ) , the only one i saw was Null nodes (still on testing small
C things , haven't tried any real thing yet :) )

I've managed to pseudo-chain ASTConsumers , i used a variation on Vlad's
idea , a custom ParseAST that accepts a vector of ASTConsumers , calls them
one by one.
I'm also getting good results with in-place AST modifications , that i chain
as separate ASTConsumers ,, that's why i need to know the exact limitations
of pretty-print , upon which i depend now

Thanks,
