Compound with expression

[kyoyama-kazusa]

I don't know whether anybody shares this idea, because I don't see anything about this idea. If duplicate, I'll be sorry for that.

Consider code:

g = g with { Prop1 = DayOfWeek.Friday, Prop2 = 13 };

Simplification:

g with= { Prop1 = DayOfWeek.Friday, Prop2 = 13 };

Complex pattern matching:

if ((g with= { Prop1 = DayOfWeek.Friday, Prop2 = 13 }) is { ExampleProp: 20 })
{
    // Code playing with 'g'...
}

I don't think putting compound assignment and condition in a single statement is necessary.
