disagreement over interface

[Hal Daume III <hdaume@ISI.EDU>]

Say I have foo.ml and I 

  ocamlc -c foo.ml

to produce foo.cmo.

Then in the ocaml toplevel, I do:

  #load "foo.cmo";;

to load the bytecode.  Now, I make changes to foo.ml and recompile it:

  ocamlc -c foo.ml

If I then go to reload it, I get:

  #load "foo.cmo";;
  The files foo.cmo
  and foo.cmo
  disagree over interface Foo

The only way I have found to remedy this is to quit my current top level, 
rerun and then load foo.cmo from there, but this is a major pain.  I 
assume I'm just missing something stupid.  Can someone tell me what to do?

Thanks!

 - Hal
