How does that make graph transformations easier and avoid issues with memory management related to those? I tried looking in the docs at your link to see (because it looks a lot more like a syntax extension for an assembler than anything that helps with the problems the author noted), but the page notes,

> Sorry, right now there is no proper documentation included other than some Examples and of course the source code. The source is well documented, though (IMHO).

and the example doesn't seem to have anything relevant to the problems identified above.
