get ss pos name returns the symbol mapped to the builtin
name. If the symbol cannot be found then
Fatal is raised.
get_opt ss name returns
Some s where
s is the symbol mapped to the builtin
Hash-table used to record checking functions for builtins.
check ss pos name sym runs the registered check for builtin symbol
name on the symbol
sym (if such a check has been registered). Note that the
bmap argument is expected to contain the builtin symbols in scope, and the
pos argument is used for error reporting.
register name check registers the checking function
check, for the builtin symbols named
name. When the check is run,
check receives as argument a position for error reporting as well as the map of every builtin symbol in scope. It is expected to raise the
Fatal exception to signal an error. Note that this function should not be called using a
name for which a check has already been registered.
val register_expected_type : Term.term Lplib.Base.eq -> Term.term Lplib.Base.pp -> string -> ( Sig_state.sig_state -> Common.Pos.popt -> Term.term ) -> unit
register_expected_type name build pp registers a checking function that checks the type of a symbol defining the builtin
name against a type constructed using the given
