[PATCH] D76196: [ASTMatchers] Extend hasReturnValue to GNU StmtExpr

[Aaron Ballman via Phabricator via cfe-commits]

aaron.ballman added a comment.

I don't think this is a natural fit for the functionality. A statement expression doesn't have a return value so much as it is a value expression that can contain multiple statements. To me, at least, this is a bit like saying the comma operator has a return value because you can do `int i; i = 1, 2, 3;` and it "returns" 3.

Can you explain a bit about why you need this matcher functionality?
