- !ruby/struct:SM::Flow::P 
  body: <tt>catch</tt> executes its block. If a <tt>throw</tt> is executed, Ruby searches up its stack for a <tt>catch</tt> block with a tag corresponding to the <tt>throw</tt>'s <em>symbol</em>. If found, that block is terminated, and <tt>catch</tt> returns the value given to <tt>throw</tt>. If <tt>throw</tt> is not called, the block terminates normally, and the value of <tt>catch</tt> is the value of the last expression evaluated. <tt>catch</tt> expressions may be nested, and the <tt>throw</tt> call need not be in lexical scope.
