[erlang-patches] Local function names in Core Erlang guards
Fri Jan 11 17:12:37 CET 2013
I wrote a really small patch to forbid local fun variables in Core Erlang guards.
There is no test case as there is no test suite for core_lint.
I know the code freeze for R16 is soon but this is really a very small thing.
