type translation_config = {
keep_special_ops : bool;
(** When [keep_special_ops] is true, then this translation uses special
Scalc AST nodes for higher-order operators like map, fold,
handle_default, etc. This is useful if the target language after Scalc
does not support nested functions like C. *)
dead_value_assignment : bool;
(** When [dead_value_assignment] is true, the translation inserts dummy
assignments of the variable being defined in the current code branch
just before raising a terminal error. This is useful for languages
like Python and their linting tools like mypy. The assignment uses the
polymorphic [Ast.dead_value]. *)
no_struct_literals : bool;
(** When [no_struct_literals] is true, the translation inserts a temporary
variable to hold the initialization of struct literals. This matches
what C89 expects. *)
