in thread hash key regular expression pattern

There is a difference, but it's a bit subtle.

With Tie::RegexpHash you set your hash keys to regular expressions and then look them up using fixed strings.

With Tie::Hash::Regex you set the keys to fixed strings and then look them up using regular expressions.

In this case, it looks like Tie::RegexpHash is the way to go.
