The older post you are referring and this thread describe the exact situation in 
your last sentence.  The limited assignment "compromise" is a common solution 
nowadays, just as this thread discusses.

Repeating "it won't work" when it has been shown to work well in several 
languages is nonsensical.  Yes, the available solutions are not perfect, but I 
still maintain "as" is less disruptive and doesn't reverse 25 year-old design 
choices, but rather works with them.
