Convert ObjectIDs to string on the model - potential side effect?

[Pierre Beaujeu]

Hello all,

For some reasons (performance, readability mainly) I don't wan't to use ObjectID.prototype.equals for comparaison but strict string comparaison (===).

I noticed Model.prototype.toObject but unfortunatly this method let ObjectIDs untouched... Can I stringify the ObjectIDs on my model without side effects? e.g. if I convert _id to a string, will mongoose still be able to save it properly?
