Subject: Should I use instance_eval or block.call

I am writing a library that will be used by others. Have been reading a
lot about procs/blocks etc, and the difference between block.call and
instance_eval pointed out in some articles was the context they are
executed in.

So if I put instance_eval in my method, the user of my lib can call
methods in a block without using an instance. Otherwise, he has to use
the instance to call a method.
That means that the user has to know whether I have used block.call in
my source or instance_eval.

Other than that, how do i decide which to use ? Are there any other pros
and cons?
