Yeah, the problem with that is that I want the /names/ of the matches,
that only returns the match. This was for library code, so the
developer passes the regex. There are workarounds, but I would have
liked to be able to do something more like
auto names = m.captures.names;
foreach (name; names) {
writeln(name,": ", m.captures[name]);
}
or even a straight AA-style foreach like this:
foreach (name, match; m.captures) {
writeln(name,": ", match);
}
it was decided that more data was needed in regex anyway, but there
was no consensus as to how that should be implemented.
