You are missing the point. I was suggesting that the use case of new
syntax might be satisfied instead by new functions, which are clearly
preferable to new syntax from the perspective your rebuttal comes
from.

Indeed, one could write those helper functions, and use them, without
any changes to Python being made at all!
