null is self evaluating, would you mind explaining the absurd redundance of #'?

Well, the fact of the matter is that you need either sharpsign quote or (function ...) to get the functional value of a name.

WTF, >>442?

CL-USER(1): null

Error: Attempt to take the value of the unbound variable `NULL'.

  [condition type: UNBOUND-VARIABLE]



Restart actions (select using :continue):

 0: Try evaluating NULL again.

 1: Use :NULL instead.

 2: Set the symbol-value of NULL and use its value.

 3: Use a value without setting NULL.

 4: Return to Top Level (an "abort" restart).

 5: Abort entirely from this (lisp) process.

[1] CL-USER(2):

The symbol nullp isn't interned so we have to juggle to read it first (interning it) and then access the function associated with it.
null doesn't have a value binding, only a function binding. Read CLtL 2.
The absurd redundance of #' is when people write #'(lambda ...)

You don't know what you are talking about, null is a self evaluating expression.
Read Steeles book, he mentions it in the first chapter or so.
#' is not for lambda expressions. You're clearly useless if you suggest that #''s usage is to prefix lambda expressions.

He means (), you faggot. Try to write null in a lisp prompt before you make an ass of yourself.

#' WAS for lambda expressions, in the old glorious days of the LispM. So, some legacy programmers (and some who don't have a clue) still use it.
BTW: Learn English so you understand the last sentence.

Liskell is not Haskell in Lisp. It's a thin layer over Haskell to change the syntax. It's just a GHC extension.
