In 06f0441 (JRUBY-6892) Enumerable#drop was changed to call #dup on every element that ended up in the result, but that might not work. Not all objects correctly implement #dup, or are even allocatable. #take was not changed, and looking at the differences between #take and #drop the only thing that stood out was that the signature of the #each call was different. Changing from Signature.NO_ARGUMENTS to Signature.ONE_REQUIRED make the issue that 06f0441 tried to fix go away.
