Conversion of OCaml-values to S-expressions
val default_string_of_float : (float -> string) ref

default_string_of_float reference to the default function used to convert floats to strings.

Initially set to fun n -> sprintf "%.20G" n.

val write_old_option_format : bool ref

write_old_option_format reference for the default option format used to write option values. If set to true, the old-style option format will be used, the new-style one otherwise.

Initially set to true.

val read_old_option_format : bool ref

read_old_option_format reference for the default option format used to read option values. Of_sexp_error will be raised with old-style option values if this reference is set to false. Reading new-style option values is always supported. Using a global reference instead of changing the converter calling conventions is the only way to avoid breaking old code with the standard macros.

Initially set to true.

val list_map : ('a -> 'b) -> 'a list -> 'b list

We re-export a tail recursive map function, because some modules override the standard library functions (e.g. StdLabels) which wrecks havoc with the camlp4 extension.
