sender class in ruby?

Anyone know how to get the sender class/module in ruby?

caller[0] is helpful to derive the filename and linenumber sending.

But knowing the class would be helpful. Can't find it any searches?

This would be impossible. You shouldn't be specialising your behaviour in a method based on the calling class anyway.

Think about it this way - the caller could be an anonymous function (proc) created in one class, then given to another one and invoked from a third place. You wouldn't get anything useful.

Instead, I'd look at what you're trying to achieve here, and think of another way to get there! :)
