Also, the lexical blocks structure from the counterexample that I provided, IMO, shouldn't pop up in practice. I can hardly imagine for which source code two lexical block chains with swapped blocks will be produced if usually lexical blocks form a tree, and "#include" directives also form a tree. It would be interesting to know about such examples.
