> provides {{sneaky*}} utility methods for hiding checked exceptions. This is
> rather unusual coding. Based on what's provided in the code I would have
> concerns as a reader that we're not handling errors properly in calling code.
> Either, we remove these methods and add proper exception handling or we add
> proper documentation on why this workaround is necessary.
