More documentation in the ouput of #show?

Often when I use #show in the Ocaml toplevel I find myself wondering why I only get the type of the value, and why I can’t get the odoc-comment in the .mli (if it exists) as well, that would save me the pain of having to go look for it in a separate file.
Has anybody considered such a feature before and/or tried to implement it in a library ?
