Personally, I'd like to see the addition of a "critical" function

requirements for extra local variables, generates optimal code,
and generates any required "goto out" automatically. You can use
it on inlined functions to avoid function call overheads if you
I think that's a *great* idea!
Wouldn't that require a change to the syntax of the c language? Not
that it's a bad idea but just don't expect to see it soon unless
someone else has already proposed it to whatever committee oversees
As an aside, Java has a construct that would help here; you can put a
"try" around code that might fail and have a "finally" block that
always gets executed:
So even though there's a "return" in the try block, the "finally"
block will still get executed before the "return".
(I've been a c programmer for years and have just recently dipped my
toes in the Java waters. Java does have some nice ideas.)
