Suggestion: Add instance modifiers to C# (and other languages)

I’d like to be able to do

someFunctionReturningY(x){ somePropertyOfY=4; … }.DoSomething();

It should also support casting without needing parentheses in the following type of statement:

Z zzz = (Z)functionReturningY{somePropertyOfZ=…; … };

 

The same pattern should work for enums too apart from object instances. It is inspired by initializers in C#, e.g. var x = new Test(){someProperty=…}. It’s just a generalization of the same pattern.

E.g. at the following scenario I want to modify an object that GetMetadataFromUI function returns

 

and currently I’m forced to write this which is way more verbose:
