P.S. This reminds me to put a roadmap of sorts on where std.regex is
going and what to expect.
Btw one thing I'm not fond of is the format specifiers, in particular:
$` part of input preceding the match.
$' part of input following the match.
` and ' are very hard to tell apart. But I guess this was based on an
existing standard? Personally I'd prefer $< and $>.
The precedent is Perl. A heavy influencer on the (former) std.regex design.

(grep for $')
Personally I'd prefer both simply gone :) Reasoning is that you can't
support these while pattern matching on the fly (say on a network
stream). Since we can't do that - anything better that is popular enough
is acceptable.
