Notation: a new annotation "compat 8.x" extending "only parsing"
Suppose we declare : Notation foo := bar (compat "8.3").
Then each time foo is used in a script :
- By default nothing particular happens (for the moment)
- But we could get a warning explaining that
"foo is bar since coq > 8.3".
For that, either use the command-line option -verb-compat-notations
or the interactive command "Set Verbose Compat Notations".
- There is also a strict mode, where foo is forbidden : the previous
warning is now an error.
For that, either use the command-line option -no-compat-notations
or the interactive command "Unset Compat Notations".
When Coq is launched in compatibility mode (via -compat 8.x),
using a notation tagged "8.x" will never trigger a warning or error.
