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!
