Assistance debugging compile time isomorphism failure to get PR #114 working
Since Saturday I've been banging my head against this one. Over at
https://github.com/anadon/graph/tree/isomorph-fix I've been trying to fix

mismatch that may not be resolvable sanely, but I want to get another set
of eyes before I just the gun and start suggesting ripping out tests.
