The Go CDK stores a Context in a struct while performing I/O:
https://pkg.go.dev/gocloud.dev/blob#Bucket.NewWriter
It could be argued that this is done for compatibility with the io.Reader
and io.Writer interfaces. However, I think this pattern, used sparingly, is
suitable for API interactions where multiple method calls are required for
a single conceptual task.
