Sometimes compromises are needed. It would be good if we had something that was neither excessive verbose nor painfully terse, required nothing but ASCII, that was similar enough to dict unpacking to suggest a connection, but without being confusable to anything else even to newbies, was self-descriptive without needing much or any explanation, cured Covid-19, brought peace to the Middle East, ended poverty, and improved the level of political discourse on social media. But I fear we may have to relax the requirements somewhat :-) My requirements for this syntax are: - it's a form of dict unpacking, so it ought to use `**` rather than overloading some other, unrelated, symbol like (say) `@` or `%`; - it ought to use a simple list of identifiers without needing extra sigils or markers on each one, say: `meta, dunder, private` rather than `:meta, :dunder, :private` or `meta=, dunder=, private=` - it ought to be something "like" an expression, rather than a mode that has to be turned on and then applies to the end of the function call; - if it actually is an expression, that's a nice bonus, but it's not essential; - it ought to look Pythonic, which is subjective; - or at least not look like "line noise", which is still subjective but it's probably easier to get agreement on what is ugly than on what is beautiful :-) It is a lot to ask.
