It allows you to put the deferred logic near the allocation/use site which I noticed was helpful in Go as it becomes muscle memory to do cleanup as you write some new allocation and it is hinted by autocomplete these days. But it adds a new dimension of control flow, which in a garbage collected language like Go is less worrisome whereas in C this can create new headaches in doing things in the right order. I don't think it will eliminate goto error handling for complex cases.
