Version 1, January 1994
Copyright (c) 1993-1994, Apple Computer

This design note removes the logical operators logeqv, lognand, lognor, 
logandc1, logandc2, logorc1, and logorc2 from core Dylan.

-------------------------------------------------------------------

Remove the logical operators logeqv, lognand, lognor, logandc1, logandc2, 
logorc1, and logorc2.

-------------------------------------------------------------------

Notes

These seven logical operators are unnecessary and may confuse users.  
They can be replaced with simple combinations of logand, logior, logxor, 
and lognot.  logand, logior, logxor, and lognot  are common in the 
languages and educational experience of Dylan's target audience, while 
the extra seven are not.
