regex
The regular expression as a string.
Most regex escape sequences just work because they are not valid Typst
escape sequences. To produce regex escape sequences that are also valid in
Typst (e.g. \\), you need to escape twice. Thus, to match a verbatim
backslash, you would need to write regex("\\\\").
If you need many escape sequences, you can also create a raw element and extract its text to use it for your regular expressions:

regex(`\d+\.\d+\.\d+`.text).
