Hi,

I think it would be awesome if the toplevel would be able to spit out
the interface to a module.

Like:

# Printf;;
and it prints out a Module = sig ... end of the module if found.

or some other facility to view this information in the toplevel. Seems
it is capable of displaying pretty much everything else...

# module P = Printf;;
module P :
  sig
    val fprintf : out_channel -> ('a, out_channel, unit) format -> 'a
    val printf : ('a, out_channel, unit) format -> 'a
    ....
  end

Or like this: (;-))

# module P = Printf;;
module P :
  sig
    val fprintf : out_channel -> ('a, out_channel, unit) format -> 'a
    val printf : ('a, out_channel, unit) format -> 'a
    val eprintf : ('a, out_channel, unit) format -> 'a
    val sprintf : ('a, unit, string) format -> 'a
    ...

Maybe *module _ = Printf ;;* would be slightly more elegant, but the
above does work.

Or if you don't want to pollute the namespace with a module called P:

# module Printf = Printf;;
module Printf :
  sig
    val fprintf : out_channel -> ('a, out_channel, unit) format -> 'a
    val printf : ('a, out_channel, unit) format -> 'a
    ...
  end
