Constructor
Create a regular expression from a string.
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).
