It may not be explicitly documented, but this is probably what you want:

[1] <USER 39> :local
Compiled lexical environment:
0: NIL
1: NIL
2: #<EXCL::SIMPLE-ERROR.0>
3: NIL
[1] <USER 40> :local 2
#<EXCL::SIMPLE-ERROR.0>
[1] <USER 41> (setf foo *)

#<EXCL::SIMPLE-ERROR.0> 
[1] <USER 42> (inspect foo)
EXCL::SIMPLE-ERROR structure instance @ #x948609 = .long item.
   0 excl-type ----> Bit field: #x3d
   1 structure-name -> The symbol EXCL::SIMPLE-ERROR
   2 -DUMMY-SLOT- -> The symbol NIL
   3 FORMAT-ARGUMENTS -> (KLASDF), a proper list with 1 element
   4 FORMAT-STRING -> A simple-string (50) that starts "Attempt to take "
[2] <USER 44><i> 


We're also in the process of releasing a programming environment, called
Composer, that would achieve the same end through windows and mouse 
manipulation.
