You can do that in your ~/.clisprc :

[5]> (set-macro-character #\)
          (lambda (stream ch) 
            (declare (ignore stream ch))
            (error "extra closing parenthesis")))

T
[6]> (+ 1 2))
3
[7]> 
*** - extra closing parenthesis
The following restarts are available:
ABORT          :R1      Abort main loop
Break 1 [8]> :q
[9]> 


Or you can even make it just a warning, ignoring superfluous closing parentheses:

[9]> (set-macro-character #\)
          (lambda (stream ch) 
            (declare (ignore stream ch))
            (warn "extra closing parenthesis")
            (values)))
T

[13]> (+ 1 2)) (* 3 4)))
3
[14]> 
WARNING: extra closing parenthesis
12
[15]> 
WARNING: extra closing parenthesis
WARNING: extra closing parenthesis
