if you do it once - why do you care about "ugly" scope_exit?

Do you mean why I care that I have to call the free function at every exit point of the scope? That's easy: because it's error prone. Defer is much less error prone.

I agree with @pjmlp - you need to write wrappers around the C api.
But if you.. > If I'm gonna write RAII wrappers around every tiny little thing that I happen to need to call once
use them just once.. so, why care about ugliness, just write ugly code just once? Code can't be perfect.
