Looks like it corresponds fairly closely to Module#module_eval.

If there is a code block available to be yielded to, it takes no
arguments and yields to the block. Otherwise, it takes at least 1
argument, a string to be eval'd. You can also supply a 2nd argument or a
3rd argument, which are used as the file name and line number,
respectively, in any error messages.
