Alone this looks like a reasonable use of auto. In a real codebase, there may be two (or twenty) different connection-like things, multiple of which may be reasonably to call in this context.
The "Hungarian notation" comment is correct - it's not strictly Hungarian notation, but annotating function (or variable) names when the language has a type system representing this same information is the same idea with the same problems as Hungarian notation.
