- !ruby/struct:SM::Flow::P
body: Both forms iterate through <em>str</em>, matching the pattern (which may be a <tt>Regexp</tt> or a <tt>String</tt>). For each match, a result is generated and either added to the result array or passed to the block. If the pattern contains no groups, each individual result consists of the matched string, <tt>$&</tt>. If the pattern contains groups, each individual result is itself an array containing one entry per group.
