perldata says your typeglob method "used to be the preferred way to pass arrays and hashes by reference into a function, but now that we have real references, this is seldom needed." And, "Much safer is to use a reference."

And your typeglob method doesn't play nicely with strict and warnings, while the reference method does.

And for opinion, I think the reference method is absolutely clear; while the * introduces a bit of mystery.
