Hi,
This patch adds a `dropReturn` combinator to `MethodHandles` that can be used
to create a new method handle that drops the return value, from a given method
handle. Similar to the following code:
MethodHandle target = ...;
Class<?> targetReturnType = target.type().returnType();
if (targetReturnType != void.class)
target = filterReturnValue(target, empty(methodType(void.class,
targetReturnType)));
// use target
But as a short-hand.
Thanks,
Jorn
