Clean up on leave
Problem
The real strength of LEAVE is that it runs
however the block is left — including an early
return.
Write a subroutine work whose body starts with a
LEAVE phaser printing Cleanup. Then, still
inside the subroutine, print Working, return
immediately, and put a say 'never reached' line after the
return. Call the subroutine. The early return
skips that last line, but Cleanup is still printed.
Example
The program prints:
Working
Cleanup
