Is str ~ regex the root of all evil, or the leaf of all good?

The consecrated terminology is:

foreach(match; match(s, r))
    foreach(capture; match)
      writeln(capture);

"Group" is a group defined without an intent to capture. A "capture" is 
a group that also binds to the state of the match.

Anyhow... this can be done but things get a tad more confusing for other 
uses. How about this:

foreach(match; match(s, r))
    foreach(capture; match.captures)
      writeln(capture);

?
