[Caml-list] Newbie: Separate compilation of interfaces, modules

["andrew cooke" <andrew@acooke.org>]

Hi,

I can't work out how to structure the following in files (there are
examples in the documentation, but all seem to be for interactive work). 
I don't know if the problem is conceptual (not understanding modules,
signatures etc) or practical (don't know what to type).

I have an interface, PersistentArray, that I define in PersistentArray.mli

Then I have an implementation, BinaryTreeArray, that I code in BinaryTree.ml

But where do I put the information that BinaryTreeArray implements
PersistentArray?  What should go in BinaryTreeArray.mli so that I can use
it as a particular implementation of PersistentArray?

The idea is that later I can define some other implementation, say
TrieArray, that can be used as the PersistentArray implementation without
changing any more code than is necessary (preferably just one line
somewhere).

Thanks,
Andrew
