<p>Groups refer to parenthesized expressions inside a regex pattern. They look
like this, where <code>exp</code> is an arbitrary regex:</p>
<ul>
<li><code>(exp)</code> - An unnamed capturing group.</li>
<li><code>(?P<name>exp)</code> or <code>(?<name>exp)</code> - A named capturing group.</li>
<li><code>(?:exp)</code> - A non-capturing group.</li>
<li><code>(?i:exp)</code> - A non-capturing group that sets flags.</li>

<p>Generally speaking, when this is true, it means the NFA is supposed to
be used in conjunction with moving backwards through the haystack. That
is, from a higher memory address to a lower memory address.</p>
<p>It is often the case that lower level routines dealing with an NFA
don’t need to care about whether it is “meant” to be matched in reverse
or not. However, there are some specific cases where it matters. For
example, the implementation of CRLF-aware <code>^</code> and <code>$</code> line anchors
needs to know whether the search is in the forward or reverse
direction. In the forward direction, neither <code>^</code> nor <code>$</code> should match
when a <code>\r</code> has been seen previously and a <code>\n</code> is next. However, in
the reverse direction, neither <code>^</code> nor <code>$</code> should match when a <code>\n</code>
has been seen previously and a <code>\r</code> is next. This fundamentally changes
how the state machine is constructed, and thus needs to be altered
based on the direction of the search.</p>
