I'm aware. To a large extent both regex-redux and pidigits are measures of the overhead of FFI for all non-C/C++/Rust languages. Rust is very cool in that one for actually using a regex engine implemented in Rust; definitely has my admiration.

As the author of Rust's regex engine, thanks. :-)

But yeah, just wanted to make sure people are actually looking at the code. The top submission for Python, for example, is not how I've ever seen anyone use regexes in Python. That's an important dimension to evaluate in these discussions! (But not the only one, of course.)

One wonders how long it will be until someone submits a Rust program that uses PCRE2.

Yeah, like "Always look at the source code."
