From: ACW at MIT-AI (Allan C. Wechsler)
In system 29.95 NWS, with microcode 669, on LISP Machine Eleven:
I hate to be a noodge, but why does (format t ...) return NIL?
This is a great inconvenience when writing code like
(and condition
(format t "Yes, it is true.")
(do-this)
(do-that)
... )
---Wechsler
For the record, I don't want FORMAT changed. I disliked this reasoning
when it was applied in Maclisp to PRINT and friends, also. The above
programming style is really poor, and I don't think we should alter the
system to encourage it. I currently feel that the use of AND and OR
as cheapo conditionals is not stylistically desirable; the above example
calls for COND, not AND.
