Retrieving optional fields

[raboof]

Wouldn't it make sense to have a variation on 'find' that returns an option instead of raising an error when no element is found?

[samoht]

yes, that would be useful!

[raboof]

Should we rename find to find_exn and change find to return an option? Or do we care deeply about backwards compatibility?

[samoht]

don't worry too much about backward compatibililty, we will just need to add some version constraints in the opam-repository for the next release.
