Request - Access to global variables in `withData` function

Currently as implemented, I don't have access to any of my spec files' global variables (i.e. they're all undefined).

However, this is only the case when my `withData` call is the direct descendant of a `describe` block. It is not an issue if the ancestory goes: `describe` -> `it` -> `withData`; but this limits my ability to output meaningful spec names, as I will then have nested `it`s (i.e. `it` -> `withData` ->`it` -> `expect`), which seems to then output all of these `spec`s at the bottom of the Karma output.

Let me know if you have any questions on my error, as I realize this sounds a little confusing!

**Edit**: Even weirder than I initially thought, I do have access to global variables, but the one I'm trying to access (an object) has all of its properties cleared out.

**Edit 2**: After looking at it more, I think the root of the problem is that Leche expects `withData` to be called as code that's a direct descendant of `describe` blocks, which in Mocha seems to not play nicely. So this way I can't have access to any global mock data that I may have. Any workaround for this with Leche?
