Basic types and definitions required throughout the system.
exception Bug of string
exception Finally of exn * exn
Raised when finalization after an exception failed, too.
The first exception argument is the one raised by the initial
function, the second exception the one raised by the finalizer.
exception Validation_error of string list
exception Unimplemented of string

read_only
Handy types for marking things read-only and read-write. One should not expose
functions for converting between read_only/immutable/read_write because the private
types expose the subtyping. Users would say "(db :> read_only Db.t)" to cast. The
difference between read-only and immutable is that someone else can change a read-only
object, while immutable never changes.

never_returns
never_returns
should be used as the return type of functions that don't return and
* might block forever, rather than 'a
or _
. This forces callers of such functions to
* have a call to never_returns
at the call site, which makes it clear to readers what's
* going on. We do not intend to use this type for functions such as failwithf
that
* always raise an exception.

val protectx : f:('a -> 'b) -> 'a -> finally:('a -> unit) -> 'b

val write_lines : string -> string list -> unit
write_lines fname lines
writes each string in lines
(plus a newline) to file
fname
.
val input_lines : ?fix_win_eol:bool -> Pervasives.in_channel -> string list
Completely reads an input channel and returns the results as a list of
strings. Each line in one string.
val read_lines : string -> string list
read_lines filename
Opens filename, reads all lines, and closes the file.
