    - [singleton_val] is now called [value],
    - [singleton_place] is now called [place],
    - [LPtr] is now called [void_ptr] and is accessed with notation [void*],
    - [LVoid] is now called [void_layout].
    - The front end now accepts `void*` as an identifier.
    The last change introduces a new Coq scope called [printing_sugar] that is only opened at the beginning of proofs in generated proof files. It defines printing notations intended at making the output of the tool closer to the syntax of the front end. In particular it defines the following notations:
    - [own l : ty], [shr l : ty], [frac {β}...
