"Variable binding depth exceeds max-specpdl-size" Error
---------------------------------------------------------
See [Issue 906](https://github.com/leanprover/lean/issues/906) for details.
[Moritz Kiefer](https://github.com/cocreature) reported that `proofgeneral`
comes with an old version of `mmm-mode` (0.4.8, released in 2004) on ArchLinux
and it caused this problem. Either removing `proofgeneral` or upgrading
`mmm-mode` to the latest version (0.5.1 as of 2015 Dec) resolves this issue.
