At least, it seems technically possible to modify the preparser to consistently make sense of this notation. If guess these are reasonable requirements for "syntactical sugar": 1) It must be easily recognisable for the preparser. I think this is the case here. 2) There is no way to interpret it in Python syntax (i.e., there can be no doubt for the preparser which syntax is being used). I think this is the case here, since having ";" after an opening [ before there is the closing ] is a syntax error in Python. 3) The lead developers must like the notation to such extent that they consider modifying the preparser for the first time after 3 years. So, probably 3) is the biggest problem.
