See 9b (1) -- interior commas do not get a space, and hence no numeric indicator

[zorkow]

That's the problem with parsing numbers that we had discussed

At the moment this is not an interior comma so there will be a visible space behind the commata, leading to the interpretation of a non-enclosed list.

I have a couple of heuristics ready that try to deal with some of these cases, in particular, preferences of relations over punctuation that could help here. But they are still somewhat immature to release into the wild. E.g., how do you classify x=123,456=y vs x=123,y=456 (note that the correct 123{,}456 is easy!).
