    test of a number of ways of invoking a method that are or look similar to SAMs
    added for: https://github.com/kilim/kilim/issues/38

    also shows off Kilim.trampoline() - ie, this class can be run with or without weaving
    if it hasn't been woven, it will automatically call the runtime weaver
