null-coalescing collection literals

[RenderMichael]

There are quite a few circumstances where a method retrieves a list, but if that list is null we instead use an empty list.

I was wondering if the current status of collection literals would allow a syntax like

object[] m1 = M() ?? []; // Would this be legal?
var m2 = M() ?? []; // Maybe even interpreting the return type of M()?

static object[]? M() { /*...*/ }

Sorry to rehash if this was explicitly discussed in the LDM, but that would be an extremely useful syntax for me.

Please discuss things related to collection literals in the collection literals discussion :)

To answer your question. Both of those would be legal.
