Summary
The tHelper interface is defined only for internal usage. We don't need a "hard" type for it as we don't define methods on it. Let's make is just a alias to the anonymous interface it represents.
Note: we are already using type aliases elswhere, and type aliases were introduced a long time ago in Go 1.9.
