Invokedynamic is just the beginning. There's lot of higher level functionality you'll need on top of it that Dynalink provides.
Dynamic linking to any plain Java object's property getters, setters, fields, methods, classes' static properties, fields, methods, constructors. Additional container operations for arrays, collections, and maps. Full overloaded method resolution, vararg handling, and type conversions; the whole deal.
Ready to use monomorphic and polymorphic call site classes. Out-of-the-box bootstrap methods. Type guards. A whole lot of wheel reinvention eliminated for you.
Automatically provides all Java Language Specification compliant type conversions, and lets you extend them with your language specific ones. Your conversions automatically become first-class citizens when being considered in overloaded method resolutions and parameter passing.
