Vim syntax highlighting for SQL strings inside Python code

On a more general level, Christian Brabandt's re-imagining of emacs' region narrowing can be a great work to work files that contain complex embedded strings.

Much like the emacs feature it is useful outside this specific use case too, and it can be a great way to perform heavy edits without needing to care about boundaries and such.
