Notation "{ x }" is reserved and has a special status as component
of other notations such as "{ A } + { B }" and "A + { B }" (which
are at the same level as "x + y");

Reserved Notation "{ x : A | P & Q }" (at level 0, x at level 99).
Reserved Notation "{ x & P }" (at level 0, x at level 99).
Reserved Notation "{ x & P & Q }" (at level 0, x at level 99).
Reserved Notation "{ x : A & P }" (at level 0, x at level 99).

Reserved Notation "{ ' pat | P & Q }"
(at level 0, pat strict pattern, format "{ ' pat | P & Q }").
Reserved Notation "{ ' pat : A | P }"
(at level 0, pat strict pattern, format "{ ' pat : A | P }").

(at level 0, pat strict pattern, format "{ ' pat : A & P }").
Reserved Notation "{ ' pat : A & P & Q }"
(at level 0, pat strict pattern, format "{ ' pat : A & P & Q }").
Support for Gonthier-Ssreflect's "if c is pat then u else v"
Module IfNotations.
Notation "'if' c 'is' p 'then' u 'else' v" :=
(match c with p => u | _ => v end)
(at level 200, p pattern at level 100).
End IfNotations.
