Improvements:
*) Enable lambda expressions to be returned from other lambda expressions
*) First cut at separating inference constraints generation from type-variable fixing

Bug fixes:
*) Case of nested method calls with lambda expression leads to spurious inference error
*) Try-with-resources inside lambda expressions lead to compiler crash
