Unless this has changed in 1.7.* or something, it still doesn't give me
a binding object I can pass to eval and such.

<SNIP>
irb(main):001:0> def foo; bar; end
nil
irb(main):002:0> def bar; caller; end
nil
irb(main):003:0> a = foo
["(irb):1:in `foo'", "(irb):3:in `irb_binding'",
"/usr/lib/ruby/1.6/irb/workspace.rb:51:in `irb_binding'",
"/usr/lib/ruby/1.6/irb/workspace.rb:51"]
irb(main):004:0> a.type
Array
</SNIP>

This is all nice enough for logging, but not for evaluating code in the
context of the 'caller-parent', which is necessary for the assert to
work.
