Larry is still considering allowing a C<FIRST> block that would do this.
It would go inside the loop block.

This will be called a C<NEXT> block. It goes inside the loop block.

This will be called a C<LAST> block. It goes inside the loop block.

Larry has been mulling over whether various types of loop should be allowed to take
C<else> blocks to accomplish this.
