- !ruby/struct:SM::Flow::P
body: "Invoked when a reference is made to an undefined constant in <em>mod</em>. It is passed a symbol for the undefined constant, and returns a value to be used for that constant. The following code is a (very bad) example: if reference is made to an undefined constant, it attempts to load a file whose name is the lowercase version of the constant (thus class <tt>Fred</tt> is assumed to be in file <tt>fred.rb</tt>). If found, it returns the value of the loaded class. It therefore implements a perverse kind of autoload facility."
