 (require mzlib/pregexp)

NOTE: This library is deprecated. Use racket/base instead.

The mzlib/pregexp library provides wrappers around regexp-match, etc. that coerce string and byte-string arguments to pregexp matchers instead of regexp matchers.

The library also re-exports: pregexp, and it re-exports regexp-quote as pregexp-quote.

Like regexp-match, etc., but a string pattern argument is compiled via pregexp, and a byte string pattern argument is compiled via byte-pregexp.
