This is a strange way to input in FriCAS, it actually defined a rule for ':'
(1) -> y:Integer == 1
Type: Void
(2) -> y:Integer == 1
1 old definition(s) deleted for function or rule :
Type: Void
(3) -> :
(3) : (y, Integer) == 1
Type: FunctionCalled(:)
As for "BOOT::|sayFunctionDeps| is undefined" error, it can be fixed
by following patch,
after the patch, ")display properties" works:
(1) -> z == 2
Type: Void
(2) -> )display properties z
Properties of z :
This is an interpreter rule.
Definition: z () == 2
