Dear GHC,

Does  ghci  have a command of           clearing  
out of all the currently defined values
(like  x  set by  `let x = 1') ? 
What about un-loading modules?
Does the user need to exit and re-run ghci in order to reset the 
created environment?
Such situation is not a tragedy, but still ...
