Description zarevucky.jiri 2010-02-03 16:45:36 UTC 
Since coalescing operator has been implemented, it would be nice (and logical) to also have a matching assignment operator.
Comment 1 Jürg Billeter 2010-03-26 19:56:44 UTC 
I don't think it's a good idea to add conditional assignment operators. If I see an assignment, I expect the right hand side to always be evaluated. This would not be the case with ??=. The other binary conditional operators (&& and ||) don't have a matching assignment operator, either.

I also don't think that self-assignment with the coalescing operator is really that common. The left hand side of ?? is always nullable while the right hand side is often non-null. Assigning to a nullable variable would often not be the best choice, in my opinion.
