Being pretty or short is not a goal of this project, nor do I see the value in such goals.

In my case, to efficiently match against a large number of IP addresses and IP address ranges:

Here is an example. Given the following list of strings:
1.2.3.4 127.0.0.1 127.0.0.2 127.0.0.11 128.0.0.1 125.0.0.* 200.0.0.1 2001:0db8:85a3:0000:0000:8a2e:0370:1300 2001:0db8:85a3:0000:0000:8a2e:0370:1330 2001:0db8:85a3:0000:0000:8a2e:0370:1337 あいうえお あいうえこ 😃😁😆😐 😃😁😆 😃😁🤣
list2regexp will return the following pattern:
^(?:1(?:(?:\.(?:2(?:\.(?:3(?:\.(?:4))))))|(?:2(?:(?:5(?:\.(?:0(?:\.(?:0(?:\.(?:.*)))))))|(?:7(?:\.(?:0(?:\.(?:0(?:\.(?:(?:1(?:|(?:1)))|(?:2))))))))|(?:8(?:\.(?:0(?:\.(?:0(?:\.(?:1)))))))))))|(?:2(?:0(?:0(?:(?:\.(?:0(?:\.(?:0(?:\.(?:1))))))|(?:1(?::(?:0(?:d(?:b(?:8(?::(?:8(?:5(?:a(?:3(?::(?:0(?:0(?:0(?:0(?::(?:0(?:0(?:0(?:0(?::(?:8(?:a(?:2(?:e(?::(?:0(?:3(?:7(?:0(?::(?:1(?:3(?:(?:0(?:0))|(?:3(?:(?:0|7))))))))))))))))))))))))))))))))))))))))))|(?:あ(?:い(?:う(?:え(?:(?:お|こ))))))|(?:😃(?:😁(?:(?:😆(?:|(?:😐)))|(?:🤣))))$
I didn’t know about this so I tried testing it out. Yes, this is possible, but requires enabling a specific flag (x when it comes to regexp2) assuming the engine even supports this feature.
