I think this would cause a warning from Sphinx, as all class/meth/func/mod/etc roles look up in the same namespace (what Georg said).

Benjamin is -1 for explicitness
I am -0 because of the ` vs. `` possible ambiguity—I prefer disabling the default role altogether
Georg, are you still +1 or should we reject this?
