It saddens me greatly to hear about that, suffice it to say new regex doesn’t use templates at all. — | |||

Templates weren't the issue.
You want to be very careful with the std.uni tables, don't initialize them at CTFE unless you can help it.
This is what my big bad PR for std.regex that was merged recently prevented. A whopping 500ms.
Either way, its fixed now thanks to time trace!
