I'm not even sure I like it, but many of the responses have denied the existence of the use case rather than criticizing the solution.
I haven't seen anyone deny that it is possible to write code like
spam(ham=ham, eggs=eggs, toast=toast)
What I've seen is people deny that it happens *often enough* to deserve dedicated syntax to "fix" it. (I use scare quotes here because I don't actually think that repeating the name that way is a problem that needs fixing.)
Sorry for being silent for agreeing with the original proposal - but indeed - I think it does happen often enough to ask for some change - doubly so with stgin/template formatting calls (It is not fun to have to maintain 3rd party code doing format(**locals() ) , and just writting every used constant twice - and _then_ having to justify to others why that, awfull as it looks, is way better than using the **locals() call. (and yes, it _does_ happen)
Is it really that awful? I mean, assuming you're sane and use .format_map. But, as was said before, most of the time it doesn't make much sense to do .format_map(locals()) as the variable you want should be part of some more-naturally accessed namespace.
, I think that there could possibly be something better than the proposed syntax -and we culd get to it - but as it is, it would eb good enough for me.
