Yeah, I think what you just stated is an issue for any type of abstraction. You really just have to examine an interface in depth before you start writing code with it to see if it's capable of supporting the functionality you need.

Only a few months ago while developing a REST API in Ruby, I implemented MongoMapper for my ORM/Database access layer. Turns out it didn't support a few things I wanted to do, so I hacked my code into little (ugly) pieces just so I could continue using MongoMapper (Didn't have time for a rewrite). I think if I would have just stuck with using the native Ruby Mongo driver, development would have taken less time and my code wouldn't look like a steaming pile of shit!

Well, you know, the native Ruby Mongo driver and Ruby itself are both abstractions, too.
