binder_restrictions : unit -> (string * string) list

SYNOPSIS

Shows the list of binder restrictions currently in force.

DESCRIBE

associate_restriction is used to control the parsing and prettyprinting of restricted binders, which give the illusion of dependent types. The list of current restrictions is found by calling binder_restrictions. There are always at least the following restricted binders: ["!","?","@","\\"].

FAILURE

Never fails.

EXAMPLE

    associate_restriction("DURING","RES_DURING");
    () : unit

    binder_restrictions();
    [("DURING","RES_DURING"),("!","RES_FORALL"),("?","RES_EXISTS"),
     ("@","RES_SELECT"),("\\","RES_ABSTRACT")] : (string * string) list
