I would totally use a Swift-style concise defer. Writing the idiomatic wrapper struct and implementing Drop is obtuse and repetitive. Both wrapper structs and the scopeguard macro approach have to be wasting compilation time.

I have a lot of FFI code paths that end up easier to understand if you use the C-style instead of the Rusty approach.

Readability and comp time should be important even in FFI code paths
