/**

 * passed arguments to be space efficient; i.e. if you  only use the public lookup, you'll get back an
 * implementation that doesn't waste space on storing the lookup object.
 * @param lookup the lookup that determines access rights at the call site. If your language runtime doesn't have
 * equivalents of Java access concepts, just use {@link MethodHandles#publicLookup()}. Must not be null.
 * @param name the name of the method at the call site. Must not be null.
 * @param methodType the type of the method at the call site. Must not be null.
 * @return a call site descriptor representing the input. Note that although the method name is "create", it will
 * in fact return a weakly-referenced canonical instance.
