/**
 *  Information for compilation of code fragments for `evaluate expression`
 *
 *  The expression evaluator works by wrapping a code fragment in a method.
 *  The free variables of the fragment are closed over by the parameters of
 *  that method, and finally the method is placed in a class.
 *
 *  This data structure contains "synthesized" descriptors for that class,
 *  method and parameter lay-out.
