--- Comment #3 from Emilio López <redorav at gmail dot com> --- Hi Andrew, Thanks for the fast reply, I understand that some things are outside the spec, but it'd be a great addition, if possible. The simplified test case you made would definitely repro the error message I get, I was just trying to illustrate the real use case it would be useful for. Thanks
