[erlang-patches] [eeps] EEP37: Funs with names

Hello,

I've opened two issues at wrangler and erlide:

	https://github.com/RefactoringTools/wrangler/issues/48
	https://github.com/erlide/erlide/issues/121

I've also patched pmod_transform (I feel sullied) to make it support named funs:

	git fetch https://github.com/nox/pmod_transform eep37

	https://github.com/nox/pmod_transform/compare/erlang:master...eep37
	https://github.com/nox/pmod_transform/compare/erlang:master...eep37.patch

Regards,
