Why? Don't you want to know where the error occurred?  ;-}

Anyway, if you are not "debugging" per se but just noodling around
in the REPL and don't want to drop into the debugger every time
you typo or violate a function signature, you might like something
like the following [not specific to CMUCL, actually]:

    > (defun my-debugger-hook (c hook)
	(declare (ignore hook))
	(when (find-restart 'abort c)
	  (princ c)
	  (abort c)))

    MY-DEBUGGER-HOOK
    > (setf *debugger-hook* 'my-debugger-hook)

    MY-DEBUGGER-HOOK
    > (/ 1 0)

And you can always undo it temporarily if you *do* want the full
debugger functionality for a specific expression evaluation:

    > (let ((*debugger-hook* nil))
	(mapcar '1+ '(12 34 foo 56)))

    Argument X is not a NUMBER: FOO.
       [Condition of type SIMPLE-TYPE-ERROR]

    Restarts:
      0: [ABORT] Return to Top-Level.

    Debug  (type H for help)

    (KERNEL:TWO-ARG-+ FOO 1)
    Source: Error finding source: 
    Error in function DEBUG::GET-FILE-TOP-LEVEL-FORM:  Source file no longer exists:
      target:code/numbers.lisp.

Again, one wonders why. One of the major *advantages* of CMUCL is
its extremely-helpful compiler notes.

+---------------

Are you sure you're getting "chat" and not just the *values*
from the COMPILE-FILE? E.g., this may look like "chat":

    > (compile-file "foo" :print nil :verbose nil)

    #P"/u/rpw3/foo.x86f"
    NIL
    NIL
    >

but it's really just the values from COMPILE-FILE. If you throw
them away, you get nothing:

    > (progn (compile-file "foo-hash" :print nil :verbose nil) 34)

    34
