The fragment of ACSL understood by the Value Analysis is limited,
albeit evolving towards increased support. Some great progress have
been made between Carbon and Oxygen: ranges and many other things in
Nitrogen, \separated and improved \initialized in Oxygen, etc.
However, user-defined predicates are currently not handled, and won't
be in Oxygen. Depending on our available time, they _may_ be present
in Fluorine.
