Subject: [Caml-list] is there a way for turning strings to "format"s?

Hi,

I would like to ask, how to do something like:

	let computed_format = Printf.sprintf "%%0%dd" 5 in
	Printf.printf computed_format 42

The above code is rejected, because "computed_format" is of type "string" whereas

        ('a -> 'b, out_channel, unit) format =
           ('a -> 'b, out_channel, unit, unit, unit, unit) format6

type was expected.

My question is: is it possible to turn strings to values that would be accepted by Printf.printf as its first parameter?
