/**
 * Inter-operability between different languages is covered by this package.
 * In case you are implementing own {@link com.oracle.truffle.api.TruffleLanguage} and you want
 * to interact with other {@link com.oracle.truffle.api.TruffleLanguage language implementations}
 * you need to use types from this package.
 * <p>
 * Different languages can exchange either wrappers of primitive Java
 * types (like {@link Integer}, {@link Double}, {@link String}), or they
 * can export their own types (if they implement {@link TruffleObject} interface).
 * Btw. One can recognize foreign object if it implements {@link TruffleObject}.
 * <p>
 * To use {@link TruffleObject} from a different language one needs to ask
 * the language to build appropriate AST for a given {@link Message}. To do
 * so use {@link ForeignAccess#node(com.oracle.truffle.api.interop.Message)}
 * and when calling it {@link ForeignAccess#execute(com.oracle.truffle.api.nodes.Node, com.oracle.truffle.api.frame.VirtualFrame, com.oracle.truffle.api.interop.TruffleObject, java.lang.Object...)}.
