Regular expressions are natively supported by the language, following Perl-like syntax. The RegEx class provides methods for matching, searching, replacing, and splitting strings based on regular expression patterns.

Here are some examples of how to use the RegEx class:

regex = RegEx("^\\d+$")

You can also define regex patterns using raw string literals to avoid escaping backslashes.

regex = RegEx(r"^\d+$")

Notice also that Klyn language support a native syntax like Perl or JavaScript for regex literals, which can be used directly without the need for escaping backslashes.

regex = /^\d+$/
