 // FuncNameInferrer is a stateful class that is used to perform name
 // inference for anonymous functions during static analysis of source code.
 // Inference is performed in cases when an anonymous function is assigned
 // to a variable or a property (see test-func-name-inference.cc for examples.)
 //
 // The basic idea is that during AST traversal LHSs of expressions are
 // always visited before RHSs. Thus, during visiting the LHS, a name can be
 // collected, and during visiting the RHS, a function literal can be collected.
 // Inference is performed while leaving the assignment node.
