Item Details
Summary Add .records getter to Map (as an extension method)
Triage to area-library

(what's this?)

from sdk.

would be a big breaking change

I hope not, because that's what I plan to do eventually.
Or, more precisely, make MapEntry be an extension type on the record type ({K key, V value}). (Can't make it implement the record type, sadly.)
Then you can safely cast .entries to Iterable<({K key, V value})>, and you can still do dynamic access to key and value.

Of course, this would all be moot if we could just remove the type when destructuring

Yes, please!

About the idea itself (if we can't get rid of the type when destructuring), it's not impossible, but it's also not particularly important when you can just write MapEntry in front and get the same effect.
Which means it's not so important that we're likely to introduce specialized implementations for the platform Map implementations (and a way to opt in to it, which requires some check in the extension method to see if the map is a platform map implementation).
