- !ruby/struct:SM::Flow::P 
  body: Returns a copy of <em>str</em> with <em>all</em> occurrences of <em>pattern</em> replaced with either <em>replacement</em> or the value of the block. The <em>pattern</em> will typically be a <tt>Regexp</tt>; if it is a <tt>String</tt> then no regular expression metacharacters will be interpreted (that is <tt>/\d/</tt> will match a digit, but <tt>'\d'</tt> will match a backslash followed by a 'd').
- !ruby/struct:SM::Flow::P 
  body: If a string is used as the replacement, special variables from the match (such as <tt>$&amp;</tt> and <tt>$1</tt>) cannot be substituted into it, as substitution into the string occurs before the pattern match starts. However, the sequences <tt>\1</tt>, <tt>\2</tt>, and so on may be used to interpolate successive groups in the match.
- !ruby/struct:SM::Flow::P 
  body: In the block form, the current match string is passed in as a parameter, and variables such as <tt>$1</tt>, <tt>$2</tt>, <tt>$`</tt>, <tt>$&amp;</tt>, and <tt>$'</tt> will be set appropriately. The value returned by the block will be substituted for the match on each call.
- !ruby/struct:SM::Flow::P 
  body: The result inherits any tainting in the original string or any supplied replacement string.
- !ruby/struct:SM::Flow::VERB 
  body: "   &quot;hello&quot;.gsub(/[aeiou]/, '*')              #=&gt; &quot;h*ll*&quot;\n   &quot;hello&quot;.gsub(/([aeiou])/, '&lt;\\1&gt;')         #=&gt; &quot;h&lt;e&gt;ll&lt;o&gt;&quot;\n   &quot;hello&quot;.gsub(/./) {|s| s[0].to_s + ' '}   #=&gt; &quot;104 101 108 108 111 &quot;\n"
