It would have been nice to see statement expressions included in C23, as

 As i understand it, WG14's plan is to eventually get lambdas into standard
C so as to unify statementexprs with Clang's Blocks and GCC's local
subroutines.
 

I've certainly seen suggestions for lambdas in C.  I'm not sure that it is a great idea to add such high-level features to C - if we want to work in C but with lambdas, C++ already supports that.  But "blocks" (borrowed from Objective-C, IIRC) are more advanced than gcc's statement expressions, so I suppose lambdas are a reasonable superset of these three extensions.
