OK, thanks - that obviously explains it. I think you are absolutely right that our previous solution was build around unspecified assumptions.

You are referring to some workaround that could mimick the old behaviour? Could you give an example? (Maybe this might be of interest for some simple "legacy cases" of ours)

From my point of view it would be convenient for some code we already have and do not need to change - but, on second thoughts, you are right: it is somewhat artificial.

EXCELLENT - this is much better than what I had hoped for. Here is another happy Babel fan!
Warm regards,
