The idea behind this PR seems great. However, I'm a little concerned about backwards compatibility. For example, this code snippet would initialize a table with two fields instead of one, which can translate in unexpected behaviour of the script:

myTable = { xmlLoadFile("file.xml") }

Although I think that most scripters only take into account the first return value currently, I wouldn't take that for granted. IMHO, a 100% backward-compatible solution would be definitely better. This PR faced a similar problem which was solved by modifying the behaviour of the function according to min_mta_version. Maybe this could be improved the same way?

Better yet, instead of adding an extra field, just use LogWarning

@Dezash , that sounds nice to me 👍 . engineLoadDFF does that too when trying to load a bad DFF, if I remember correctly.
