## Add regular expressions

You can define a <abbr title="A regular expression, regex or regexp is a sequence of characters that define a search pattern for strings.">regular expression</abbr> `pattern` that the parameter should match:

(The proof is the same as Section 7 of Boehm and Adve's paper cited above.)
This property is called DRF-SC.

The intent of the formal definition is to match
the DRF-SC guarantee provided to race-free programs
by other languages, including C, C++, Java, JavaScript, Rust, and Swift.
