I'd be in favor of a nice syntax for named mapping unpacking.
But while we are at discussion - I'd point out it is "possible" (not easy)
with
current day syntax, by abusing the command "import" -
One can set appropriate import hooks that would enable
either for the current module, or maybe, in a context ("with") block
the use of import targeting a variable - so, the syntax
from mymap import key1, key2
can work.
Downside: it will be much slower than an assignment.
I have something similar working, but it is currently based
on monkey patching builtins.__import__ - upgrading it to properly
using the import machinery is on the roadmap.
